Class of Signals in the Invention
[0063] Physical signal l-th is a complex periodic function, SF.sub.l(t), which describes the specific time variation of the physical event (natural and artificial alike). [0064] Electric signal, SE.sub.l(0, is the output signal from a general transducer. Its variable (in the time and/or frequency domain) is in bijection with the one which pertains to the natural or artificial physical event SF.sub.l(t).
[0065] The general l-th independent electric signal, SE.sub.l(t), which transports the contents of information (or energy) to be processed, may appear in the following two algebraic form: [0066] m.sub.l(t): a periodic complex function, where its frequency is f.sub.BBlf.sub.0 and its frequency bandwidth is BB.sub.lBW.sub.0 and index l=1, . . . , L: m.sub.l(t)=m.sub.l exp(-j2f.sub.BBlt). [0067] SI.sub.l(t): a general composed periodic complex function. It is a composed function of m.sub.l(t). SI.sub.l(t) may assume forms two: [0068] 1. Polynomial function, composed by R components (where R is an integer number, the value of which is included into an [1; ] interval). An FDM signals sequence e.g. each rth Polynomial (where r=1, . . . , R) presents a limited independent frequency bandwidth, BB.sub.rBB.sub.l, which is not overlapped and which is consecutive to the other one. The resultant composed by the R Polynomial frequency bandwidths is BB.sub.l=.sup.R.sub.r=1BB.sub.r. [0069] 2. Single general modulated function (any modulation, such as digital and/or continuous ones, angular and/or amplitude related ones) with a frequency carrier fo and a generic m.sub.l(t) modulating signal. In the easiest case, e.g.:
SI.sub.l(t)=F[m(t); f.sub.0]=m.sub.l exp[j2(f.sub.0-f.sub.BBl)t].
[0070] Each l-th (where l=1, . . . , N) SI.sub.l(t), electric signal function, has its own BB.sub.l independent frequency bandwidth, Furthermore:
BB.sub.lf.sub.slf.sub.BBl; .sup.L.sub.l=1BB.sub.lLf.sub.0; .sup.L.sub.l=1.sup.M.sub.m=1BB.sub.lLMf.sub.0; and BW.sub.0BB.sub.l. [0071] S.sub.l(t)=S[m(t); f.sub.0] is a complex l-th time function (or S.sub.l(j) in frequency domain) generated by the invention implementation. Its independent and limited frequency bandwidth is BW.sub.SlBB.sub.l. Its central frequency is f.sub.Slf.sub.0. In the easiest case: f.sub.Sl=f.sub.0-f.sub.BBl
[0072] so that:
.sup.L.sub.l=1BW.sub.Sk(L)BW.sub.0 and .sup.L.sub.l=1.sup.M.sub.m=1BW.sub.Sl(L)MBW.sub.0 [0073] S.sub.lkm(t)=S[S.sub.l(t); l; k; m] is a complex lkmth function generated by the invention method. It depends on S.sub.l(t) and index l, k, and m. Its independent and limited frequency bandwidth, for example, is BW.sub.SlkmBB.sub.l[(l-1)K+k]m. Its central frequency is f.sub.Slkmf.sub.0[(l-1)+k/K]). In the easiest case: f.sub.Slkm (f.sub.0-f.sub.BBl) [(l-1)+k/K]
The Invention Concept
[0074] HSCS system develops a linear combination of L assigned independent not orthogonal functions (or algebraic scalar polynomial functions), m.sub.l(t) (or SI.sub.l(t), in bijection with L spatial (3-D) orthogonal complex vectors functions. All the orthogonal complex vectors generated by the invention method are correlated to the frequencyf.sub.0.
[0075] The HSCS (3-D) orthogonal complex vectors identify an univocal (3-D) complex vector space, which is an algebraic Hilbert space.
[0076] The complex vector space assigned frequency bandwidth is BW.sub.RF if each of the independent m.sub.l(t) (or SI.sub.l(t)) frequency bandwidth BB.sub.l is limited, too.
[0077] Each HSCS l-th orthogonal vector generated by the invention is equipped with the same requested temporal phase, f.sub.0t, and an assigned l-th (3-D) specific spherical spatial phase, .sub.l(lf.sub.0; l).
[0078] .sub.l(lf.sub.0; l) is assigned by the invention method and is time independent. Once f.sub.0 is set, .sub.l(lf.sub.0; l) belongs to the l relative index value only. The invention sets .sub.l(lf.sub.0; l) as composed by a pair of time independent planar phases: [0079] Azimuth phase, the value of which depends on l, is included into an [0; L2] interval [0080] Tilt phase, the value of which depends on If.sub.0 ,is included into an [(90-/2L), (90-/2L)] interval
[0081] Conversely, by the invention method HSCS it is possible to detect the same vector space orthogonal complex vectors (
[0082] Separately or simultaneously HSCS, of the invention, extracts all the required 3-D orthogonal complex vectors which are necessary and sufficient to reconstruct all the required L m.sub.l(t) or SI.sub.l(t).
[0083] The operating principle of the invention method is based on the HSCS operator, which is an integral part of the invention as well as a characteristic one of it. According to the invention method, the HSCS is in turn composed by four basic operators, which are described as follows:
HSCS.SUB.LKM .Transform Operators
[0084] The transform operator indicated as HSCS.sub.LKM (see
G.sub.e(.sub.0) Transducer Operators
[0085] The invention transducer operator is defined by its assigned transfer function G.sub.e(.sub.0).
[0086] G.sub.e(.sub.0) transforms the HSCS.sub.LM output in physical signal (see
G.sub.e(.sub.0) Sensor Operators
[0087] The invention sensor operator is defined by its assigned transfer function G.sub.c(.sub.0)
[0088] G.sub.c(.sub.0) transforms the physical signal in a specific electrical signal (see
[0089] Usually, G.sub.c(.sub.0) is the inverse of the G.sub.e(.sub.0) or in many others applications G.sub.e(.sub.0)1/G.sub.e(.sub.0) is possible. Its implementation depends on the specific invention application. HSCS uses G.sub.c(.sub.0) to detect simultaneously or separately all the LKM orthogonal complex vectors which are correlated to f.sub.0.
HSCS.sub.LKM.sup.1 Anti-Transform Operators
[0090] HSCS.sub.LM.sup.1 anti-transform operator (see block 16000 of
HSCS.sub.LKM.sup.1[HSCS.sub.LM]=.sup.L.sub.l=1.sup.K.sub.k=1.sup.M.sub.m=1HSCS.sub.lkm.sup.1[S.sub.lkm(t)].
[0091] HSCS.sub.LKM.sup.1 of the invention reconstructs all the L requested m.sub.l(t) or SI.sub.l(t) independent functions.
[0092] Therefore, HSCS of the invention is composed by two different parts which are considered as two separate subsystems: [0093] 1. Emitter: G.sub.e(.sub.0)*HSCS.sub.LM=G.sub.e(.sub.0*.sup.L.sub.l=1.sup.K.sub.k=1.sup.M.sub.m=1S.sub.lkm(t)], related to an HSCS.sub.LM linear transform operator and G.sub.e(.sub.0) transducer operator process. The subsystem generates a complex vector space (Hilbert space) and a requested related complex field. The subsystem is characterized by a vector complex scalar coefficients 3 LKM3LKM matrix. The complex matrix developed by the invention method, e.g. in the electromagnetic case, describes the complex scalar field components amplitude distribution which satisfies the wave equation in the paraxial approximation (see ref. [10]). [0094] 2. Collector: G.sub.c(.sub.0)*HSCS.sub.LKM.sup.1=G.sub.c(.sub.0)*HSCS.sub.LKM.sup.1[.sup.L.sub.l=1.sup.K.sub.k=1.sup.M.sub.m=1S.sub.lkm(t)], related to G.sub.e(0) sensor operator and HSCS.sub.LM.sup.1 linear anti-transform. The subsystem detects and extracts the complex orthogonal vector correlated to f.sub.0. The subsystem is characterized by a vector complex scalar coefficients 3LKM3LKM matrix. The matrix of the subsystem, developed by the invention method, is the inverse of the first one above.
OAM Spatial Phase Resultant
[0095] OAM spatial phase resultant generated by invention assigned complex vector 3LKM-dimensional space is indicated in the following:
.sub.LM(Lf.sub.0; L)=[.sub.lkm(lf.sub.0; l; k; m); L, K, M]
[0096] Once f.sub.0 is set, the invention .sub.LM(Lf.sub.0; L) belongs to the L, K and M parameters values which are assigned by the invention method. .sub.LM(Lf.sub.0; L) is time invariant and is assigned by the invention method.
l-th Harmonic Phase
[0097] l-th harmonic phase of invention is: f.sub.lt=lf.sub.0t.
Relative Carrier Frequency of the I-th OAM Mode
[0098] The relative carrier frequency of the l-th OAM mode is generated by the invention method. It is related to the fundamental frequencyf.sub.0=2.sub.0. It depends on the specific application, f.sub.0 and l index. Its expression, e.g. in the simplest case, is:
.sub.RFSl=.sub.0-.sub.BBSl; and d/T.sub.0=.sub.RFSl.
[0099] Besides, according to the invention method what results is the following: [0100] l-th azimuth phase: .sub.RFSl=l d; and =2-.sub.RFSl. [0101] l-th tilt phase: .sub.RFSl=.sub.RFSl/(4l); and =90-.sub.RFSl; d=.sub.RFSl
[0102] channel index: l=1/tg.sub.RFSl.

Without excluding any other development surroundings, they are listed below in illustrative but not restrictive way: [0104] 1. Physical: natural and/or not natural (artificial) and/or Synthetic (electronics, and/or mechanics, etc . . . . ); [0105] 2. Theoretical Numerical; [0106] 3. Theoretical Algebraic.

Typology of Implementation
[0112] Five possible typologies of implementation are considered. Each of them is to be considered as an integral part of the invention.
[0113] They are identified by their specific level of implementation complexity. The invention method implements each of them by using a different architecture of the HSCS. Each typology allows a different improving factor of the related phase error margin. That phase error margin factor is inversely proportional to the specific level of implementation complexity. They are all feasible and listed below: [0114] a. Continuous chirp and continuous phase. Its implementation complexity level is high.

General Description of Invention Implementation
[0120] With reference to the figures, according to the invention, a method is supplied to canalize and transfer a multiplicity of periodical independent physical signals represented by SF.sub.l(t), complex functions in the time domain t, where L is an integer number, the value of which is included into an [1; ] interval and l=1, . . . L, each one occupying a BB.sub.l, independent frequency band, e.g. BB.sub.l=[(f.sub.0-f.sub.BBl), f.sub.0], Some of such independent signals are e.g.: electrical, electromagnetic, digital and/or analog, mechanical oscillations, pressure waves, optical signals. Starting from these independent signals the invention method generates a single complex signal, which is the resultant signal of L orthogonal components. Each l-th of that orthogonal components is in bijection with the respective SF.sub.l(t). The single complex signal is correlated at a frequency f.sub.0 and occupies a single frequency bandwidth equal to BW.sub.RF=max [BB.sub.l], the largest band among said BB.sub.l bands. The invention method performs the following steps: [0121] A. acquiring (11000) the physical signals SF(t) and transforming them (11000) into electrical signals by means of one or more transducers; [0122] B. extracting (11000) from each electrical signal of the previous step the relevant information content as modulation function m.sub.l(t); [0123] C. performing (11000) the Fourier Transform of m.sub.l(t), obtaining the function m.sub.l(j); [0124] D. generating (12100), for each modulation function m,(/co), a corresponding periodic digital signal P.sub.l(j)=S.sub.l(j) having carrier frequencyfo and modulation function m.sub.l(j); [0125] E. generating (12100), for each periodic digital signal P.sub.l(j), a pair of signals in quadrature; [0126] F. generating (12100), for each pair of signals in quadrature, mentioned in step E, K*M pairs of signals PP.sub.lkm(j)=S.sub.lkm(j), where K and M are integer numbers, the value of which is included into an [1; ] interval and k=1, . . . , K as well as m=1, . . . , M. Each pair of signals PP.sub.lkm(j) is generated through the following steps performed subsequently in any order or at the same time: [0127] performing KM chirp modulations, each characterized by a corresponding frequency increment f.sub.lkm=[(l-1)+k/K] (f.sub.0--f.sub.BBl) with varying k, in a time interval T=T.sub.0 at a clock frequency f.sub.c2LKMf.sub.0; [0128] performing KM phase linear modulations. Each of K*M phase linear modulations is characterized by a corresponding phase increment .sub.lkm=-l[1-(K-k)/K] (m/M)2 with varying k and m, at a clock frequency of e.g. f.sub.ck2LKMf.sub.0; [0129] G. under sampling (12200) said pair of signals PP.sub.lkm(j) at a frequency f.sub.0 thus obtaining a pair of canalized signals PP.sup.0.sub.lm(j) which by construction have a spatial phase (3-D) orthogonal to each of the other (L*K*M-1) signal pairs and moreover they are correlated to f.sub.0; [0130] H . vector summing (12200) all the L*K*M pairs of orthogonal PP.sup.0.sub.lkm(j) components thus obtaining a pair of LKM-dimension signals PP.sup.0(j) occupying band BW.sub.RFf.sub.0; [0131] I . sending the LKM-dimensional signal PP.sup.0(j) to a signals emitter-transducer (13000) tuned to f.sub.0, which performs whatever polarization.
[0132] According to the invention, step H mey be also realized by a simple collection node of all the orthogonal signals produced in step G.
[0133] According to the invention, steps E and F may be also inverted.
[0134] According to the invention, steps E and/or F and/or G and/or H and/or I may be also performed at the same time.
[0135] According to the invention, the transducer of step I may be also a signal transmission means with unitary transfer function (e.g. a cable connector).
[0136] According to the invention, it is further provided a method for the extraction of a plurality of periodical physical signals represented by complex functions in the time domain t SF.sub.l(t) where L is an integer number the value of which is included into an [1; ] interval and l=1, . . .

[0137] The extraction starts from a single signal correlated to a frequency f.sub.0 occupying a band whose width is equal to the largest band among said bands RB.sub.l, BW.sub.RF=max[BB.sub.l], wherein the following steps are performed: [0138] J. detecting (15000) by means of a sensor tuned tof.sub.0, which performs whatever polarization, said complex single signal to obtain PP.sup.0 (j)=HSCS.sub.LM; [0139] K. applying (16100) a complex correlator, at frequency f.sub.0, with a clock frequency f.sub.ck, to the signal detected by said sensor, thus obtaining LKM pair of signals, PP.sup.0.sub.lkm(j)=HSCS.sub.LKM.sup.1(S.sub.lkm); [0140] L. performing (16200), for each one or single one values of l=1, . . . L, KM contemporary convolutions, with a clock frequency f.sub.ck, of each signal pair PP.sup.0.sub.lkm(j), the KM convolutions being configured to extract KM respective chirps with frequency shift f.sub.lkm=[(l-1)+k/K] f.sub.0-f.sub.BBl) and an azimuth phase delay .sub.lkm=-l[(K-k)/K] (m/M)2in an interval T.sub.0 from said signals pair, obtaining corresponding pairs of signals with k=1, . . . K and m=1, . . . M for each l; [0141] M. summing (16200) the KM components of each l value, PP.sub.l(j), obtaining all the independent modulation functions m.sub.l(j) from said single signal with l varying; [0142] N. performing an Fourier Anti-Transform (16100) of m.sub.l(j) and thus obtaining corresponding modulation functions m.sub.l(t); [0143] O. transforming (17000) if required m.sub.l(t) into SF.sub.l(t) by one or more transducer.
[0144] According to the invention, said an only signal may be also the signal emitted by said emitter-transducer 13000) of signals tuned to f.sub.0, according to any claims 1 to 5.
[0145] According to the invention, the polarization of step I may be also the same or is different from the polarization of step J.
[0146] According to an aspect of the invention, in step F and/or correspondingly in step L, the value of M and/or K and/or L is infinite, thus obtaining infinite continuous chirps and linear phase modulation Components, wherein the summation is replaced by integral operation.
[0147] According to an aspect of the invention, the starting periodic physical signal set is subdivided into a plurality of periodic physical signals, to each element of the plurality being applied the steps of the method.

After being filtered by the anti-alias Polyphase one of 11002 block, the signal is sent to the sampler of 11003 block which could be a Serial Digital to Digital or an Analog to Digital standard converter, at a frequency rate of f=f.sub.CK. The frequency rate of the example has been set to f.sub.CK2LKMf.sub.0. The output of 11003 block is sampled and, in case conveniently de-modulated by 11004 block. The output of 11004 reaches the entry of the optional stage 11005. The 11005 output, corresponding to complex vector m.sub.l(t)=m.sub.l exp[j(2f.sub.BBlt)] sampled at f.sub.CK, is the output of this process phase of the invention.
[0168] Optionally, this output can be further processed by a 11006 FFT stage to extract the data related to the m.sub.l(t) message frequency spectrum. The aim of this optional process is to generate control data to be sent in cascade to a standard controller of 11007 block.

[0173] The Register control data designated to the specific information of the SSB delta phase, assigned by the invention, and contained in the 12108 block, enter the combiner, 12110 block of
[0174] Then, each element of the I & Q pair is auto-correlated by a first resonant stage 12114, having a multiplier tuned to f.sub.RF as algebraic model. This tuned multiplier is built by a couple of synchronous digital resonators put in parallel and f.sub.0 correlated (at least for a small phase error of proportional to .sub.BBl/.sub.0). Those synchronous digital resonators work simultaneously, at the same temporal and angular conditions, and on the same signal m.sub.l(t)) linked.
[0175] The two I and Q pairs out bounding the 12114 block are respectively represented by two synchronized polynomials. Those synchronized polynomials identify an infinite number of simultaneous intermodulation products related to the same typical single carrier frequency f=f.sub.RF m.sub.l(t) (having a small proportional phase error less than the corresponding .sub.Sl/.sub.0). The two I and Q pairs enter the second resonant 12115 stage. This second resonant 12115 stage has an algebraic model of a multiplier. Inside the 12115 stage, each simultaneous component related to each of the two input sequences, is modulated by each of the identical and simultaneous components of the other one sequence present there.
[0176] The I and Q pair output from 12115 block enters a digital low-pass filter FIR 12116 having f.sub.1dB=(f.sub.0-f.sub.BBl)[(l-1)+k/K]. The low-pass filter FIR 12116 is in charge of harmonic suppressing having f>(f.sub.0-f.sub.BBl)[(l-1)+k/K] frequency, which is typical of the l-th sequence couple I and Q.
Complex Under-Sampler 12200 of FIG. 1
[0177] The output sequence pair (I and Q) of 12216 block of
[0181] Here a 12218 block complex double mixer (one cosf.sub.0t, and the other sinf.sub.0t) generates two quadrature outputs, for each I and Q. These output signal pairs have been generated with a general complex vertical and horizontal polarization, designated as x.sup.VI and x.sup.HI (for 1) and as x.sup.VQ and x.sup.HQ (for Q), each respectively with cosf.sub.0t or sinf.sub.0t carrier.
[0182] Combiner, 12219 block, follows in cascade, and performs separately two vector additions in a 3-D space. It follows that, those two resultants vectors (V and H respectively indicated) are both correlated to .sub.thefo carrier, and each in quadrature (90 out of phase) to the other one: [0183] The one V as: x.sup.VI +x.sup.VQ [0184] The other H as: x.sup.HI +x.sup.HQ. [0185] 2. A linear polarization (with typical complex Non-TEM mode). [0186] In this case, each of all the LKM pairs outgoing from the previous 12217 stage, is sent to the 12220 block. Here the LKM components are, first of all, respectively correlated with a f.sub.0 frequency by two quadrature digital complex mixer (one cosf.sub.0t, and the other senf.sub.0t). The respective output components of the two mixers are here in-phase. Because they are orthogonal too, then here they are one to each other added and correlated with a f.sub.0 frequency. [0187] Optionally this purpose is implemented by 13023 block of
[0188] Optionally, each of the LKM output components outgoing from 12119 or 12120 blocks, enter in a D/A converter (12221) (in case an Analogic field to be generated is required). Output 12221 block is the input of 12222 block, a low-pass or a pass-bandwidth filter (also optional). In the example explained here, it is a pass-bandwidth filter BW.sub.HSCS=BW.sub.RF in charge of letting go each orthogonal component overlapping in the BW.sub.0 band.
Emitter Transducer 13000 FIG. 1
[0189] For simplicity, here in the most general case, it is an Operator that, based on the polarity whatever assigned (linear, circular or even elliptic) by the previous stage, generates the algebraic field depending on each I and Q pair outputs from 12119 or 12120 preceding stages (see
[0190] The output signal from 12222 block enters 13023 block. This block provides a transfer faction equal to G.sub.e(.sub.0) already described.
[0191] Actually, the transducer is optional: for the easiest case like a data transfer over a data network (wired network) the transducer might not be used. The equivalent is obtained setting the transferring functions =1(G.sub.e(.sub.0)=G.sub.c(.sub.0)=1).
Field, 14000 of FIG. 1
[0192] 13023 block output is an algebraic expression representing a field that occupies a BW.sub.0 bandwidth allocated by HSCS.sub.LKM, in an infinite complex 3-D space.

[0195] All those complex 3-D modes occupy the same assigned bandwidth BW.sub.0 defined by the frequencies falling in the interval (e.g. here f=[(f.sub.0-f.sub.BWo), f.sub.0], and all are f.sub.0 correlated.
[0196] The sensor, like the transducer above, is actually optional. In effect, in the easiest case of a simple data transfer over a data network (e.g.: wired network), the sensor is not needed. This is the same as putting the sensor and transducer transfer functions to 1 (G.sub.e(.sub.0)=G.sub.c(.sub.0)=1).
Complex Extractor 16000 of
[0197] Here the activated L modes HSCS.sub.LM are extracted (individually or simultaneously according to the invention implementations) from any point of the field and at every t instant. Each l-th linear combination can be continuous or discrete, depending on application cases. Each l-th linear combination is represented by a complex periodic vector algebraic expression .sub.0 correlated, and it is composed by 3LKM orthogonal vectors having 3LKM unit-vectors. Referring to
[0198] Optionally, a proper filter (16126 block of
[0199] In case all the L modes together are the matter of interest, then the optional filter will be a low-pass one, in order to select the frequencies contained in the [0, Lf.sub.0] interval. It is not needed, and can be skipped, in case of a data transfer on a digital data network.

[0201] Then, this stage sends the samples to 16128 stage (see
[0202] The output signal (I e Q) is sent to a LKM Polyphase filters bank. Each LKM filter is built by three stages in cascade that works at a frequency clock of f.sub.ck: [0203] 16229 block of
[0206] The last two cascade blocks (16230 e 16231) together realize a convolution (matched Filter) that selects each lkm-th component of the orthogonal LKM ones. The sequence order of these stages can be optionally changed.
[0207] The LKM Polyphase filters bank can be realized merging the 16229, 16230 and 16231 stages in a single decimationcompressor bank made up of one Polyphase filter that processes the LKM modes together (all or some of them).
[0208] The 16231 outputs are then combined by L combiners 16232 (optionally only 1), grouping them conveniently based on the corresponding l, k and m indexes. Each combiner sums the related KM outputs, having l index, to rebuild the l-th signal m.sub.l(t) used as the input of 16233 stage. 16233 stage is a bank that executes a Fourier transform, FFT. Here (

[0216]
[0217] The lkm-th Register data control related to each l-th m.sub.l(t) output signal of 11007 block of
[0218] Each of the 12100 generators (see
[0219] The specific carrier information lkm-th Register control data assigned by the invention are collected by 12108 block, here e.g. the SSB delta phase.
[0220] The chirp delta phase specific information lkm-th Register control data, assigned by the invention, is collected by 12109 block. The Register control data is used to synthesize the lkm-th chirp signal into the DDS of the invention.
[0221] Each lkm-th chirp signal is f.sub.0 correlated and it is produced by a S.sub.l(t) carrier having a frequency of f.sub.RF defined by the invention for a period T=T.sub.0.
[0222] In 12109 stage the following values are set: [0223] slope lkm=[(l-1)+k/K](f.sub.0-f.sub.BBl/T.sub.0 [0224] initial phase .sub.loss=0
[0225] This chirp modulation causes S.sub.l(t) a frequency linear shift of f.sub.lkm=[(l-1)+k/K] (f.sub.0-f.sub.BBl).
[0226] The value of f.sub.lkm is established by HSCS invention method, and e.g. it is computed using a MatLab code program.
[0227] The whole process of direct digital synthesis, is implemented by the invention, providing a clock frequency of f.sub.cK, the same one of all LKM expressions of HSCS, S.sub.lkm.
[0228] 12108 and 12109 stages outputs enter the combiner (see stage 12110 of
[0229] The 12110 block output of data added together are sent to 12111 block, which represents the invention phase accumulator.
[0230] Therefore, based on the data provided by 12108 and 12109 stages, each lkm-th phase accumulator 12111 outcomes the incremental phase value to be sent to 12113 block which is a look up table.
[0231] For every clock pulse, stage 12113 synthesizes a pair of digital sample, a real part I and an orthogonal imaginary part Q, of an assigned complex periodic function.
[0232] Please note that the accumulator input data bit number is N (where N is conveniently selected in order to achieve the resolution on the basis of the assigned frequency).
[0233] In turn, stage 12111 has a data bit number=PN as output.
[0234] The pair related to the 12113 block output digital signal S.sub.lkm=S.sub.lkm[f.sub.RF, .sub.lkm(lf.sub.0; l; m)], enters 12115 block.
[0235] 12115 block is a linear phase modulator that produces the lkm-th I and Q pair f.sub.0 related.
[0236] The lkm-th pair is the sub mode component having 3LKM unit vectors of the sequence.
[0237] The stage 12115 performs an algebraic model multiplier tuned to f.sub.RF. Each element of the I & Q pair is auto-correlated by the resonant stage 12115. In the stage 12115 each one of the two identical replicas of each I & Q pair, entering the two input stage, is modulated by other simultaneous one.
[0238] The I and Q pair output from 12115 block enters a digital low-pass filter FIR 12116. For example, a filter with f.sub.1dB=f.sub.0-f.sub.BBl[(l-1)+k/K]. is in charge of harmonic suppressing having f>(f.sub.0-f.sub.BBl)[(l-1)+k/K] frequency, which is typical of the l-th sequence couple I and Q.
[0239] The 12115 output represents a direct synthesis of a signal, S.sub.lkm(t), linearly modulated both in phase (linear Shift) and in frequency (chirp). S.sub.lkm(t), generated by the invention, is provided with a real part I and with an imaginary part Q squared. S.sub.lkm(t) is related to f.sub.0 frequency and turns out to be orthogonal to all the other (LKM-1) similarly synthetized by the invention (
[0240] The output generated by the two identical filters (I and Q) 12116 are synchronous signals (apart from a little phase error proportional to f.sub.BBl/f.sub.0) algebraically represented by a linear combination having lkm order compared with a fundamental frequency f.sub.RFl.

[0254] Each lkm-th chirp signal is f.sub.0 related and it is produced by a S.sub.l(t) carrier having a frequency of f.sub.RF defined by the invention for a period T=T.sub.0.
[0255] In 12109 stage the following values are set: [0256] slope lkm=[(l-1)+k/K](f.sub.0-f.sub.BBl)/T.sub.0 [0257] initial phase .sub.loss=0
[0258] This chirp modulation causes S.sub.l(t) a frequency linear shift of f.sub.lkm=f(l-1)+k/K] (f.sub.0-f.sub.BBl).
[0259] The value of f.sub.lkm is established by HSCS invention method, and it is computed using a MatLab code program.
[0260] The whole process of direct digital synthesis, is implemented by the invention, providing a clock frequency of f.sub.CK, the same one of all S.sub.lkm LKM expressions of HSCS.
[0261] 12108 and 12109 stages outputs enter the combiner (see stage 12110 of
[0262] The 12110 block output data are added together and are sent to 12111 block, which represents the invention phase accumulator. Therefore, based on the data provided by 12108 and 12109 stages, each lkm-th phase accumulator 12111 outcomes the incremental phase value to be sent to 12112 block.
[0263] 12112 block collects the phase shift Register control data too, which are dedicated to the specific linear phase shift modulation assigned by the method. They are used to synthesize the lkm-th phase shift modulation of the carrier S.sub.l(t) f.sub.0 correlated signal with the specific phase shift, .sub.lkm, into the DDS of the invention. The invention defines the lkm-th azimuthal incremental phase shift value. E.g. in the case considered in
.sub.lkm=-[(l-1)+.sub.lk](m/M)2=-l[1-(K-k)/K](m/M)2
where .sub.lm and .sub.lmk are related to the instantaneous phase linear term of the lkm-th component S.sub.lmk(t) and both are computed by the invention method (e.g. using a Matlab code program).
[0264] The 12112 block sums the data related to the output 12111 block with the one collected by its phase shift Register section.
[0265] The 12112 block output data are added together and are sent to 12113 block which is a look up table.
[0266] For each clock impulse, stage 12113 synthesizes a pair of digital samples, one for the real part I and the other for the orthogonal imaginary part Q, of a corresponding digital complex signal of an assigned complex periodic function.
[0267] Please note that the accumulator has a number of bit data N as input from registers (where N is conveniently selected in order to achieve the resolution on the basis of the assigned frequency).
[0268] In turn, stage 12111 has a number of bit data=PN as output.

Description of a Code Program Tool for Invention Method Parameters Computation
[0294] The program (eg. in Matlab code) used to compute the method parameter, according to the invention, is valid for all the implementation environments considered above (see
[0295] Following the computed system HSCS design parameters, according to the invention: the elementary spherical spatial phase increment, .sub.0(M; f.sub.0; .sub.0); all the lkm-th vectors coefficients; all the lkm-th spherical spatial phase increments, .sub.lkm(lf.sub.0; l; k; m); all the lkm-th azimuthal spatial phase increments, Olk.sub.m; all the lkm-th tilt spatial phase increments, .sub.lkm.
[0296] Furthermore, if required, the tool emulates the complete emitter subsystem HSCS.sub.LKM. For instance, for the electromagnetic case, the tool computes the Poynting Vector and the specific OAM.
[0297] The single resulting complex signal, generated by the invention, identifies a specific three-dimensional (3-D) complex vector space and 3LKM unit vectors, algebraically represented by the invention. e.g. as a general linear combination like:
PP.sup.0(j)=.sup.L.sub.l=1.sup.K.sub.k=1.sup.M.sub.m=1S.sub.lkm=.sup.L.sub.l=1.sup.K.sub.k=1.sup.M.sub.m=1C.sub.LMSlkm exp[-j.sub.lkm(lf.sub.0; l; k; m)].
[0298] In the electromagnetic (EH) case eg., the tool computes the Poynting Vector in every related complex vector space EH field point, then in every propagation axis point too. That is possible simply solving the Maxwell equations with respect of the block 12200 (
Properties of the Invention
[0299] The HSCS of the invention system generates an 3LKM dimensional algebraic Hilbert space with 3LKM unit vectors. The complex vector space is characterized by an L independent limited occupied frequency bandwidth, BW.sub.0.
[0300] In the most general case, the HSCS complex vector space generated by the invention is characterized by 3LKM complex component vectors. All of them are:
[0301] each other orthogonal [0302] related to a single central frequency typical of the resultant apart a smallest phase error belonging to .sub.sl/.sub.0 ratio.
[0303] Each Complex Vector is Provided with: [0304] a spatial spheric phase .sub.lkm(lf.sub.0; l; k; m) assigned by the invention and to which corresponds a characteristic spatial azimuthal phase .sub.lkm and a tilt spatial pahse .sub.lk. Those phases are detected by HSCS depending exclusively on l, k and m indexes (in addition to f.sub.0, and f.sub.BBl). [0305] The partial derivative of the first order of the spatial speric phase both for t and z (wave propagation axis) turns out to be null, in other words it does not belong to t not to z, actually t and z .sub.lkm(lf.sub.0; l; k; m)/ z=costant and furthermore .sub.lkm(lf.sub.0; l; k; m)/ t=costant (if the event occurs in an homogeneous medium). [0306] .sub.lm(lf.sub.0; l; k; m) is not variant along propagation axis z as well as with respect to time.
[0307] Once provided specific f.sub.cK, L, K and M which are assigned by the invention method with the requested f.sub.0, the HSCS system allows: [0308] No Processing Gain losses [0309] Processing Gain exclusively proportional belong to L, K and M. [0310] Channel Capacity gain proportionally increasing with the L, K and M values.
[0311] Such gains occur because the system is capable to process also the longitudinal component power (or informative) contributions (originated by not zero value of E/z as well as H/z). As well known in technical literature the last mentioned properties should be impossible to achieve with former invention method.
[0312] The invention HSCS develops a field that, e.g. in the electromagnetic, is equipped with assigned OAM for any required value of: [0313] L Number, and/or central frequency, and/or occupied frequency band BW.sub.O, and/or transducer physical dimension and topology, and/or sensor in use.
[0314] Such OAM is stable, invariant and differs from zero independently of: [0315] A Time [0316] Distance between the two blocks 13000 and 15000 of
[0317] The actual channel capacity (setting, for instance for the easiest case: K=M=1) provided by the invention method HSCS, C.sub.HSCS, as well known in technical literature, is computed by the expression:
C.sub.HSCS=2(L)BW.sub.0.
[0318] Provided the same available bandwidth, BW.sub.0, the channel capacity C.sub.HSCS is greater than the one C.sub.BWo, allowed by former invention systems. As a matter of fact,
C.sub.HSCS>C.sub.BWo=2BW.sub.0, furthermore Lim.sub.per L.fwdarw.C.sub.HSCS=.
[0319] The last expression guarantees that invention method generates a whole defined and algebraically continuum system, which is valid in an unlimited complex scalar as well as vector space.
[0320] The HSCS structure, both algebraic and implemented, does not present any singularity species, neither at its extreme, nor along its boundary.
[0321] Therefore, HSCS generated by the invention is a continuum at the infinite and along the assigned complex vector space longitudinal axis. On the contrary, in the former invention methods, it is impossible to achieve that last property.
[0322] Such complete HSCS system generated by the invention, transfers the power which is allocated using L orthogonal vectors. The L orthogonal vectors frequency bandwidth BW.sub.RF of complex vector resultant is equal to the maximum independent one, BB.sub.', related to the L input signals 1=1, . . . , L, BW.sub.RF=max[BB.sub.l].
[0323] Therefore, the L1 orthogonal complex mode resultant occupies a frequency bandwidth, BW.sub.occupiedBW.sub.RFBW.sub.0, while the utilized actual bandwidth, BW.sub.effective, effective, according to the invention method is always greater than the resultant one BW.sub.occupied:
BW.sub.effective=.sup.L.sub.l=1BB.sub.Sl>BW.sub.occupied
[0324] It is to be underlined that such performances, which would be impossible to achieve without our invention, increase the efficiency of: [0325] the Transfer channel [0326] the Store space [0327] the Signal [0328] sent out across a link [0329] Radiated towards any natural physical phenomena (i.e., atmospheric or climatic ones or else) in order to create an interference leading to an adequate control action.
[0330] Furthermore the invention method implementation, as high efficiency 2.sup.nd order wide frequency bandwidth power channeling and energy harvesting directly generates voltaic energy. It directly converts the available harvested energy, the one related to any TEM+DEM 1.sup.st order linear moment (LM) and Angular moment (AnM) (Electromagnetic, acoustic, gravitational, thermodynamics, pressure, optic, mechanic) detected along the wave propagation axis. As well-known AnM spherical spatial 2.sup.nd order wave beams power is about 80 dB greater than LM azimuthal spatial 1.sup.st order waves or wave beams.
[0331] The invention method allows to direct detect a Black Hole Gravitational signals with a 2.sup.nd order visibility degree >1/2. Usually the gravitational signal intensity is about 10.sup.22. As well-known in literature, the complex mutual (in a space-time domain) coherence measurement of such Gravitational wave requires to analyze an extremely short bandwidth (in the ideal case it is =0), and an instantaneous time resolution, , that in the most favorable case, turns out to be inversely proportional to the square frequency observed bandwidth value (BW.sub.0) or the wave coherence period, .sub.0. Such direct measurement especially when >>.sub.0>1/BW.sub.0 could be impossible using any former method, because its 1.sup.st order visibility degree <<1/2.
[0332] The invention method allows to allocate or to measure any generated not zero resultant Poynting vector value along propagation axis of any twisted swirling field equipped with complex TEM, non-TEM, or divergent mode too.
[0333] The complex vector space is immune from any possible interferometry error due to destructive planar (2-D) interferences. Actually each of all its orthogonal complex 3LKM-D vectors components is equipped with one characteristic orthogonal spherical (3-D) spatial (time invariant) phase, .sub.lkm(lf.sub.0; l; k; m).
[0334] The invention method has three degrees of freedom available to set .sub.lkm(lf.sub.0; l; k; m). Such degrees of freedom are: the fundamental frequency f.sub.0; the lkm-th frequency mode lf.sub.0=f.sub.lkm (or tilt plane ); the azimuth spatial phase l=.sub.lkm (or azimuth plane ). Then, because of its 3-D spatial phase, .sub.lkm(lf.sub.0; l; k; m), the invention method is immune from destructive planar phase ambiguity.
[0335] Such design three degrees of freedom available are the ones requested, and sufficient, to guarantee the generation of the LKM complex vectors space component being: [0336] 3-D spatial orthogonal; [0337] Each correlated whatever required frequency value f.sub.0; [0338] Each extractable without processing method losses.
[0339] On the contrary, the former invention methods and/or systems have less degrees of freedom available (e.g. at the most only: f.sub.0 and l): thus, they are not able to eliminate planar phase ambiguity with any f.sub.0 and l values because they lose the longitudinal component.
[0340] The invention method, HSCS, is in the same way efficiently applicable to measure near as well far distance fields, because of its planar interferometry error immunity.
[0341] The operator, according to the invention, develops both linear and quadratic, spherical wave timespatial (mutual) phases equation terms. Such terms are originated setting or detecting both spherical wave phases first and second time space derivatives. They contribute to generate the required complex or eventually full imaginary 3LKM-D TEM, non-TEM, or Divergent spherical (3-D) modes which satisfies the wave equation with a Paraxial approximation. Usually former methods neglect such terms as well as the longitudinal modes components.
[0342] The invention HSCS performs a greater approximation degree because it processes the complex or full imaginary OAM mode which are neglected or ignored by all the former invention methods. In Physics literature, such specific modes are well known as non-TEM, or Divergent mode [Electromagnetic (DEM) or Electrical (DE) or Magnetically (DM) Polarization].
[0343] As well known in technical literature, all the last-mentioned properties should be impossible to be achieved at once with the former invention methods and/or systems (see ref. [10] and [13]).
[0344] HSCS is applicable for any periodic complex function with frequency f=f.sub.0 which is included into a Low Frequency and Millimeter Wave (MMW) range interval.
[0345] HSCS is applicable for any guided or free light or laser light (e.g. Laguerre Gaussian Beam model) propagation space.
[0346] HSCS is applicable for any guided or free EM wave propagation Rx/Tx system, which TEM field is or not equipped with OAM and whatever polarization (e.g. twisted and/or skewed and/or Rx polarization different from Tx one).
[0347] HSCS is applicable for any guided or free EM wave propagation Rx/Tx system, which non-TEM TE or TM complex field mode are equipped with longitudinal not zero E or M component.
[0348] HSCS is applicable for any guided or free EM wave propagation, which divergent complex or full imaginary field mode are equipped with different Rx polarization kind compared with the Tx one.
[0349] HSCS is applicable for any base band electric signal.
[0350] HSCS is applicable for any signal which has been whatever modulated. E.g. as following: [0351] Analog modulation: AM, PM, FM; [0352] Digital modulation: QPSK, MSK, and so on . . . ; [0353] TDM, FDM;
[0354] HSCS develops systems for: information signal OAM modulation and de-modulation (mode-demod), from both base band and already up converted.
[0355] HSCS develops systems for: Spread Spectrum (SS) modulations, e.g. Direct sequence (SS-DS), see ref. [1].
[0356] HSCS develops a complex scalar function describing the distribution of a twisted field amplitude which satisfies the wave equation applicable to light and/or laser beam. It could be one of the following: [0357] Pseudo Gaussian [0358] Spherical [0359] Hyperboloid
[0360] Such distribution is developed independently by the topological characteristics of the specific sensor.
[0361] The method of the invention, e.g. by single contemporaneously observation of the frequency wide spectrum of each one of the array antennas, develops a three-dimensional, 3-D, Early universe Tomographic interferometer process with 3LKM unit vectors. Such Early universe quadratic order radio telescope observation turns out to be without planar (azimuth) phase error and ambiguity. Therefore, it is full compliant with the requirements of the innovative quadratic models used in the Astrophysics research post processors new generation, which elaborate the data from radio telescope observation.
[0362] The method of the invention, besides the space requirement, power consumption and costs decrease, empowers the radio telescope performances efficiency. On the contrary all the last-mentioned properties should be impossible to achieve with former methods and/or systems preceding the invention.
Invention Advantages and Applications Following some examples of invention applications: [0363] 1. Application example of Collector subsystem for detection, observation and measure of radiation coming from any evenly bodies, see ref. [13], which are far hundreds of billions of head and shoulders above us. Here as e.g. is considered the invention application specific case in Square Kilometer Array (SKA) program. In that case, HSCS according with the invention method, uses its ability to correlate and process, in a single concentrated local processor, both the linear and orbital angular momentum in order to extract the requested tomography information data from the whole early universe radiation frequency spectrum (for SKA mission: from the low band one 50 MHz up to the highest band five frequency, 25 GHz), which is detected by whatever single assigned local % tuned antenna of the SKA antennas arrays stations. On the contrary all the lasts mentioned properties should be impossible to achieve with former SKA methods and/or systems preceding the invention. .sub.0 is assigned according the invention method. In this case the invention method performs a 3LKM unit vectors interferometry process which allows an early universe tomography without planar phase (both azimuth and tilt) or planar ambiguity detection (destructive multi path or Doppler, etc., that are eventually highlighted by grating lobes increasing or by a very low mutual visibility degree value, <1/2).
[0364] Such 3-D Early Universe Tomography approximation order, according with the invention, is quadratic. That is why it is compliant with the innovative last generation quadratic numerical simulator research models, which are already available to elaborate the data from astrophysics SKA observations to reconstruct a required coherent early universe scale. In that example the method of the invention, in addition to the decreased dimension, power consumption and costs, is capable to improve the SKA radio telescope performances efficiency. The efficiency improving factor is proportional to the following values: [0365] LKM [0366] A Saved Antennas (not used) composing the array which, therefore, might be used for other missions or services.
[0367] On the other end all the last mentioned properties should not be achieved with former methods and/or systems preceding the invention. [0368] 2. Application example of emitter subsystem e.g. for weather and hurricanes forecasts, prevention and control. Here is a selection of a suitable number of frequencies, e.g. N (N is a integer number ) f.sub.n (with n=1, . . . , N). N and f.sub.n are selected based on statistical analysis of previous opportune climatic observations, preferably developed according to the invention Extractor sub system (above) too.
[0369] An emitter sub system according with the invention here develops a required radiation composed by LKM (or NLKM) pressure waves. Each one is characterized by a central frequency value f.sub.0 (or f.sub.n) and opposite phase value respect to the phase one of the LKM (or NLKM) statistical previously observed e.g. with the invention method. The intensity, the central frequency, and the spatial phase characterizing each LKM (or NLKM) component radiation conveniently emitted by HSCS according with the invention allows a softening action on the physic natural components before statistically selected which possibly are present. Such radiated LKM (or NLKM) components may invert the natural event (here is considered e.g. Hurricane event) by softening its action depending on the values assigned to N, L, K, and M which are separately or assembly used to implement the N subsystems, according with the invention. Such implementation method is the same of electromagnetic case, except for introducing a specific electric/pressure signal transducer rather than electromagnetic/pressure one. [0370] 3. Application example of emitter subsystem e.g. emitter and extraction system for Satellite Communication which is equivalent to the one described to implement EM one with circular polarized transmitter and receiver antennas. The possible suitable different satellite station signals LKM number to be assigned, compared with the ground control one, belongs by specific compatibility and requirements of the spaceship or space orbited station typology. Therefore, it is possible reduce wasteful and eliminate the not required receiving and transmitting satellite channels. The invention method improves sensitivity of former systems preceding the invention too. [0371] 4. Setting LKM high value (not acceptable in former systems preceding the invention) the method allows to detect the complex OAM mode included in weak fundamental with real mode far distant radiations which usually should be neglected or lost (as e.g. in Astrophysics radio telescope observations) [0372] 5. The invention allows to assign the gauge transverse related to the spherical OAM of the complex field. It allows to improve the energy related the emitted and/or extracted linear moment by a real TEM mode planar system, according with the invention. [0373] 6. The invention is applicable to implement systems or models both analogue and digital e.g. in: Physics; Mechanics; Dynamics; Acoustics; Geology; Clinics; Metrology; Interferometry; Meteorology; Astrophysics; Electronics; Radar; Navigation Assistance Services (Space, Atmospheric, Ground, Naval, Satellite); Communications; energy harvesting; Optoelectronics; Bio-Medical and Bio-Engineering; Monitoring; Security; Civil; industrial, military, data transmission; numerical data and/or video and/or audio signals compression and spreading in any multi points link multi ends emitters and users. [0374] 7. The invention allows observation and measurement of the partial second time derivative of all the variable describing any physic complex event which occurs in any environment. On the contrary all the lasts mentioned properties should be impossible to achieve with former methods and/or systems preceding the invention. [0375] 8. Furthermore, the invention method allows opportunities to open new applications fields e.g. the following: [0376] I. Nuclear Physics; [0377] II. Gravitational Physics; [0378] III. Energy harvesting; [0379] IV. Nuclear Fusion clean energy generation; [0380] V. Sustainable nuclear not radioactive nuclear energy; [0381] VI. Astrophysics see ref.[13]; [0382] VII. Medicine, e.g. in DNA particles computation; [0383] VIII. Wing Power in nautical as well in aeronautics (e.g. that occurring in high vortex state or located into so called Wing vortex extremity). [0384] IX. Dynamics Fluidity of ships outline in Navigation as well in Aeronautics; [0385] X. Eco environment and climatology: prevention measurements and control of macro and micro climatic and meteorological phenomena due to vortex motions. E.g.: pressure wave and air masses or magmatic fluid or solid mass motions (earthquakes, Vulcans, landslide, tornado, whirlwind, etc.) [0386] XI. Geology: pressure quadratic variation measuring in order to prevent ground earthquakes and landslide; [0387] XII. Data compression to memories storing; [0388] XIII. Communication: channelization and storage of any analogue and digital data information signal as well as the resultant channelization of a multi sub channelization components developing according with the invention both physically and numerically. [0389] 9. Application example as electric wide frequency bandwidth wave beam Power generator, transmission, energy harvesting and converter, HSCS system is implemented using: the Analogic wide frequency bandwidth HSCS.sub.LKM transform operator configuration of the invention as power transmitter shown in figures from 1 to 7, and the Analogic wide frequency bandwidth HSCS.sub.LKM.sup.1 as power extractor and voltaic converter shown in figures from 10 to 15. [0390] 10.Application example as electric Analogic wide frequency bandwidth Power extractor and converter, HSCS system is implemented using simply: the Analogic HSCS.sub.LKM.sup.1 as power extractor and voltaic converter shown in figures from 10 to 15. Such configuration is valid to extract and convert and or measure any typology of linear (LM) and/or quadratic (2.sup.nd order AOM) energy (electromagnetic, and/or gravitational, and/or thermodynamic, and/or mechanics, and/or optic, and/or etc. . . . ). Such HSCS.sub.LKM.sup.1 invention implementation named 2.sup.nd order -Wave-Volt converter allows to an 80 dB efficiency gain value greater than the former method one. [0391] 11.Application example as 2.sup.nd order Bio-power frequency meter and/or 2.sup.nd order Bio-impedance meter to perform any kind of human health check about: blood, hart, lang, DNA, RNA, tumor or cancer cells, etc. . . . In such application, according to the invention are to use both the invention operators: the transform operator HSCS.sub.LKM (as reference radiation generator) and the anti-transform operator HSCS.sub.LKM.sup.1 (as power spectrum meter). [0392] 12.Application example as 2.sup.nd order Seismic sensor, according to the invention, is to use the anti-transform operator HSCS.sub.LKM' (as power spectrum meter). [0393] 13.Application example s 2.sup.nd order Thermodynamic sensor for example in Meteo phenomena control and/or prevention such as Hurricane, is to use, according to the invention, the anti-transform operator HSCS.sub.LKM.sup.1 (as power spectrum meter). It allows a time spatial analysis of any environmental observed event complex 2.sup.nd order 3-D mutual visibility. [0394] 14.According to the invention HSCS.sub.LKM performs a radio electromagnetic health therapy system. It radiates any short bandwidth at any extremely high wave beam frequency at any time-space (period-distance) value. [0395] 15.Application example as 2.sup.nd order gravitational time-space wave beam detector system for black hole analysis and studies applications. In such cases, as in Ligo (USA) or VIRGO (Italy), is to be used the full HSCS system composed by both the invention transform operator HSCS.sub.LKM and anti-transform operator HSCS.sub.LKM.sup.1. Such system performs a required time space high frequency and extremely short bandwidth wave beam radiation as well as detects the time space 2.sup.nd order complex 3-D visibility of observed physic event [0396] 16.Application example as 2.sup.nd order gravitational time-space wave beam direct detector system. As well-known gravitational wave beam intensity is about 10e-22 eV. Such value is extremely weak vs. space noise. In that case, according to the invention is to use the anti-transform operator HSCS.sub.LKM.sup.1. It detects both the first and second time space derivatives of spherical (3-D) spatial phases (azimuth and tilt) related to the observed gravitational 3-D wave beam. It allows to extract a complex 2.sup.nd order mutual visibility using any requested sample rate to independently analyze any frequency bandwidth in any coherence period (generally is requested a very long coherence period)
Invention Feasibility
[0397] The present invention feasibility occurs because of the following.
[0398] First of all, a suitable very large scale integration (VLSI) technological state of art is already available which is useful to implement present invention method. E.g. innovative and consolidate architectures and microelectronic numerical synthesis techniques are already available to develop generalized form of the transfer function algorithms according to the invention. Such architectures are possible because the state of art of ASIC as well FPGA as well GPU technology.
[0399] In addition to that, there are available programmable and reconfigurable mixed signal ASIC technology tools innovative architecture and numerical technique in order to process very high speed (MMW) complex periodic functions and signals.
Invention Applicability Limits
[0400] The invention method generates and processes infinites Hilbert algebraic spaces, I valid for every L value integer number comprised in [1; ] interval, for every K value integer number comprised in [1; ] interval, for every M value integer number included in [1; ] interval. Obviously actual invention applicability limits belong to the trade off between implementation costs and advantages.
[0401] Furthermore, the trade off critical point belongs to application typology and environment. [0402] A. E.g. in Emitter (Canalization) and/or Extractor (Universe evenly Bodies Radiations Detection and Measure) System Applicability Belongs: [0403] I. Acceptable LKM signal phase error value due to the respective clock signals mismatching phase. [0404] II. Specific implementation technology (ASIC, FPGA, GPU or other) used to develop the complex modulators (Cirp and linear phase shift). The implementation technology defines optimum clock frequency, data rate, frequency bandwidth, consumption and power dissipation values [0405] B. Limits in Data Storing and Compression Belong: [0406] I. Specific implementation technology (ASIC, FPGA, GPU or other) used to develop the complex modulators (Cirp and linear phase shift). The implementation technology defines optimum clock frequency, data rate, frequency bandwidth, consumption and power dissipation values [0407] II. Trade-off between specific temporary and storing memory sizes requested in the different applications. Anyway the canalized data compressing and transferring requires data memories, then invention benefits are a result of a specific case by case trade-off. Furthermore, it is to consider in the receiver the possibility to select or not the interest required channels only.
In both A and B below already it may be considered that the optimum LKM value is: LKM10.sup.15
[0408] Furthermore, e.g. in specific hurricane climatic control and prevention emitters subsystems(e.g.: Stepped Chirp and Continuous Linear Phase Shift of
