  • Publication number: 20240168147
    Abstract: Embodiments of an ultra-wideband (UWB) transceiver are disclosed. The UWB transceiver includes a transmitter and a receiver. The receiver has a first antenna and a second antenna. The first antenna and the second antenna are separated by a first distance, d. The receiver is configured to use the first antenna to receive the transmitted signal and use the second antenna to receive the transmitted signal, develop a range, r, between the transmitter and a selected one the first and second antennas, and develop a path difference value, p, develop an (x, y) location of the transmitter relative to the receiver as a function of d, r, and p.

  • Patent number: 11921185
    Abstract: An ultra-wideband (“UWB”) communication system comprising a transmitter and a receiver having two antennas. An UWB signal transmitted by the transmitter is received at each of the antennas. By comparing the carrier phases of the received signals, the phase difference can be determined. From this phase difference and the known distance, d, between the antennas, the Cartesian (x, y) location of the transmitter relative to the receiver can be directly determined.

  • Patent number: 10075210
    Abstract: In an ultra-wideband (“UWB”) receiver, a received UWB signal is periodically digitized as a series of ternary samples. During a carrier acquisition mode of operation, the samples are continuously correlated with a predetermined preamble sequence to develop a correlation value. When the value exceeds a predetermined threshold, indicating that the preamble sequence is being received, estimates of the channel impulse response (“CIR”) are developed. When a start-of-frame delimiter (“SFD”) is detected, the best CIR estimate is provided to a channel matched filter (“CMF”). During a data recovery mode of operation, the CMF filters channel-injected noise from the sample stream. Both carrier phase errors and data timing errors are continuously detected and corrected during both the carrier acquisition and data recovery modes of operation. The phase of the carrier can be determined by accumulating the correlator output before it is rotated by the carrier correction.
