Abstract: 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.

Abstract: A signal transmitter may include a waveform synthesis circuit and a signal transmission circuit. The waveform synthesis circuit may store values of a reference waveform for a selected channel of the signal transmitter, and use the stored values to generate values of reference waveforms for one or more other channels of the signal transmitter. The waveform synthesis circuit may further include a sampling boost circuit to generate one or more additional values for the reference waveforms. The waveform transmission circuit may generate signals for the channels of the signal transmitter based at least in part on the values of the reference waveforms, and transmit the signals via one or more antennas.

Abstract: Example systems, devices, media, and methods are described for tracking one or more movable objects and presenting virtual elements on a display in proximity to the tracked movable objects. One or more ultra-wideband (UWB) transmitters are mounted to each movable object in a physical environment including at least two synchronized UWB receivers. The receivers calculate a current location of each movable object. A plurality of portable electronic devices, including one or more eyewear devices, are paired with the receivers in a network. A localization application determines a current location of each eyewear device. A rendering application presents one or more virtual elements on a display as an overlay relative to the current movable object location and in relative proximity to the current eyewear location. The physical environment is represented by a static mesh. A time synchronized tracking application identifies moving items that are not coupled to a UWB transmitter. The rendering application presents the virtual elements on the display in accordance with the static mesh and the moving items.

Abstract: A digital pre-distortion system can inversely model a power amplifier of a system to linearize the transmitter. A complex baseband model for digital pre-distortion based on a narrowband signal assumption is unworkable for an ultra wide band Cable television application. Predistortion can use a true wide band model including real-valued basis terms, obtained from a real-valued signal. When raised to a power, both even and odd harmonics or both odd or even other non-linear terms are represented and negative frequency fold-over can be accounted for. A Hilbert transform can be applied. Compressed sensing can be used to reduce the number of basis terms in the true real wide band model to generate a sparse model. Sparse equalization can be added to improve the stability of the digital pre-distortion system.

In one embodiment, an ultra-wideband (UWB) receiver is configured to: receive an interference signal from a source positioned outside a monitored region; receive a composite signal transmitted from a tagged object moving about a playing field within the monitored region, wherein the composite signal comprises a location signal and a component of the interference signal; detect whether the component of the interference signal exceeds a threshold value; and adjust, via a processor, filtering of the composite signal to attenuate the component of the interference signal based on whether the component of the interference signal exceeds the threshold value. Some embodiments provide for filtering of the composite signal using a combiner while others employ a tunable notch filter. Corresponding systems, methods, and computer-readable storage medium are also provided.
