摘要： An ultra-wideband (“UWB”) communication system comprising a transmitter and a receiver. In one embodiment, the symbol mapper circuit in the transmitter is adapted, in a first mode, to develop symbols having the number of pulses as currently defined in the 4z Standard; and, in a second mode, to develop symbols having fewer pulses than as currently defined in the 4z Standard. In an optional third mode, each data bit is mapped to a single pulse.

摘要： 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.

摘要： An ultra-wideband (“UWB”) communication system comprising a transmitter having two transmit antennas and a receiver having a single receive antenna. Respective selected portions of the UWB signal are transmitted by the transmitter via each of transmit antennas is received at the receive antenna. By comparing the phases of the received signal portions, the phase difference of departure can be determined. From this phase difference and the known distance, d, between the transmit antennas, the Cartesian (x, y) location of the transmitter relative to the receiver can be directly determined.

摘要： In an ultra-wideband (“UWB”) receiver, a received UWB signal is periodically digitized as a series of ternary samples. During a carrier acquisition mode, 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, 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.

摘要： In a receiver facility in an ultra-wideband communication system, a dual-mode circuit adapted to operate in a selected one of three operating modes without changes in circuit topology: a calibration mode adapted to render the circuit substantially independent of circuit component mismatches; a frequency comparator mode adapted to indicate whether the frequency of a first periodic signal is larger or smaller than the frequency of a second periodic signal; and an early-late detector mode adapted to indicate whether the 1st rising edge of the first periodic signal arrived sooner or later than the 1st rising edge of the second periodic signal applied.
