Within many applications impulse radio based ultra-wideband (IR-UWB) transmission offers significant benefits for very short range high data rate communications when compared with existing standards and protocols. In many of these applications the main design goals are very low power consumption and very low complexity design for easy integration and cost reduction. Digitally programmable IR-UWB transmitters using an on-off keying modulation scheme on a 0.13 microns CMOS process operating on 1.2V supply and yielding power consumption as low as 0.9 mW at a 10 Mbps data rate with dynamic power control are enabled. The IR-UWB transmitters support new frequency hopping techniques providing more efficient spectrum usage and dynamic allocation of the spectrum when transmitting in highly congested frequency bands. Biphasic scrambling is also introduced for spectral line reduction. Additionally, an energy detection receiver for IR-UWB is presented to similarly meet these design goals while being adaptable to address IR-UWB transmitter specificity.

In some implementations, a transmitting UWB device may determine a number of information bits of a payload to communicate via UWB. The transmitting UWB device may select, based on the number of information bits, a codeword length from a selection of available codeword lengths with which to encode the payload using a low-density parity-check (LDPC) encoding scheme, wherein the selection of available codeword lengths include a first codeword length, a second codeword length, and a third codeword length, wherein the third codeword length is longer than the second codeword length, which is longer than the first codeword length. The transmitting UWB device may transmit the payload using one or more codewords having the selected codeword length.

A communication apparatus using electromagnetic pulses comprising a signal generating means for generating and transmitting data in at least one non-oscillating electromagnetic pulse as a communication signal; a signal processing means for receiving at least one non-oscillating electromagnetic pulse, and processing the one or more pulses to derive useful information; at least one antenna for sending and/or receiving signals; a time keeping means for providing time spacing variation for transmitting said pulses; a time spacing pattern library for providing known spacing patterns; a comparator for comparing a received signal with signals from said spacing pattern library to thereby identify the communication pulse, whereby the communication pulse can be distinguished from sparks, radio, and background noise.

Systems, methods, apparatuses, and computer readable media are disclosed for associating a radio frequency identification tag with a participant. In one embodiment, a method is provided for associating an unassociated RF location tag with a participant. The method may include determining an unassociated RF location tag to be associated with the participant, receiving sensor derived data from one or more sensors, determining an identity of the particular participant using the sensor derived data, and associating the identity of the particular participant with the unassociated RF location tag.

A method for generating an ultra-wideband signal is provided. The method comprises the steps of generating at least one ultra-wideband pulse envelope comprising a main pulse and a precursor pulse, the precursor pulse being shorter in length and lower in amplitude compared to the main pulse, and modulating a carrier signal in amplitude such that the envelope corresponds to the at least one ultra-wideband pulse envelope and such that the carrier signal within the main pulse is phase-shifted with respect to the carrier signal within the precursor pulse.
