Some embodiments include a system, method, and computer program product for managing the Ultra Wideband (UWB) systems, especially when the UWB system is collocated with another wireless system (e.g., WiFi) to transmit and/or receive UWB signals with an occupied bandwidth (OBW) that satisfies a UWB OBW standard (e.g., a UWB OBW>=500 MHz.) In some embodiments a TailBit signal (e.g., a periodic signal at a selected frequency) is added to a UWB packet to generate frequency components at the selected frequency that enables the power spectrum of the TailBit UWB signal to satisfy the UWB OBW standard. In some embodiments an altered code sequence is used to generate an altered spread signal, where the altered code sequence reduces or removes a frequency component peak near DC frequency of the power spectrum of an altered UWB signal, resulting in altered UWB OBW that satisfies the UWB OBW standard.

Asynchronous stream generation and processing techniques are described that support implementation of an asynchronous stream mote in which one or more analog sensor signals are used to generate one or more asynchronous streams. On-device operations processing of the one or more asynchronous streams may be performed before transmission of the result(s) to other system components (e.g., peer motes or higher-level system components).

Methods and devices for transmitting and receiving data through biological tissue using ultrasonic pulses are described. Methods of the present invention may set an initial time-hopping frame length and an initial spreading code length for data transmission. A request-to-transmit may be sent from a transmitter over a control channel at the initial frame and code length. The receiver may respond to the transmitter with a clear-to-transmit packet having feedback information. The feedback information can be used to improve a forward time-hopping frame length and a forward spreading code length. Embodiments of the invention may involve a body area network or body surface network comprising a plurality of implanted sensor nodes operating according to the disclosed invention.

A log periodic antenna is used in a communication system that utilizes multiple channels to drive distinct frequency sub-bands within an ultra-wide band. The driving elements are active and specifically tuned to the operating sub-band of the channel. Each driving element may be synchronized via a single local oscillator. Driving element includes a modem and analog-to-digital converters to digitize a portion of the signal intended for the sub-band within the channel. Actively driven log periodic antennas can jam an ultra-wide band of the spectrum.

A system for pulse based wideband signaling comprises a transmitter that performs physical layer encoding of both digital and analog data into a pulse repetition rate signal, and modulation of the pulse repetition rate signal into wideband radio frequency pulses, and transmission of the pulses as a wideband RF signal, a receiver that performs physical layer demodulation of the wideband RF signal into a pulse repetition rate signal, and decoding of the pulse repetition rate signal into digital and analog data, wherein the system provides improvement in controlling and balancing the variables of bandwidth, signal to noise ratio, range, and power consumption.

In an electronic device and an operation method thereof according to certain embodiments, the electronic device may include: a first communication circuit configured to perform a first communication using an ultra-wide band (UWB) communication scheme and a processor. The processor may control the communication circuit to: identify, based on a characteristic of data to be transmitted using the first communication circuit, a frame length of the data to be transmitted; determine, based on the identified frame length, a peak voltage of a signal containing the data to be transmitted; and transmit the data using the signal having the determined peak voltage.

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 whilst being adaptable to address IR-UWB transmitter specificity.

Systems and methods for reduced interpath interference for ultrawideband (UWB) wireless communication are disclosed. In one aspect, a wireless communication device employs a systematic and non-random pulse-hopping scheme to introduce variable distances between pulses to reduce collision rates from interpath interference. In exemplary aspects, the scheme optimizes avoidance of collision rates for distances between paths of up to thirty nanoseconds (30 ns). The use of an optimized grid will be stable regardless of position of the user, thereby avoiding transmission drops and improving the user experience.

In one embodiment, a method is provided for determining play data that at least includes correlating at least one tag to a participant; receiving blink data transmitted by the at least one tag; and determining tag location data based on the blink data. The method further includes receiving participant role data; comparing the tag location data to participant dynamics/kinetics models based at least in part on the participant role data; determining participant location data based on the comparing the tag location data to the participant dynamics/kinetics models.
