摘要： In an RF system comprising a first transceiver (96) and a second transceiver (98), a first transmission, T1, by the first transceiver (96) allows the second transceiver (98) to determine two possible valid angles of arrival, ±θ1, of T1. A second transmission, T2, from the second transmitter (98) to the first transmitter (96) containing θ1 and a bearing, α1, of a known fixed anchor relative to the second transmitter (98), allows the first transmitter (96) to determine two possible valid angles of arrival, ±θ2, of T2. From θ1, α1, θ2, and a bearing, α2, of the known fixed anchor relative to the first transmitter (96), the first transceiver (96) can determine the valid angle of arrival of T2.

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 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. By comparing the carrier phases of two receivers separated by a known distance, d, the angle of incidence, θ, of the signal can be determined.

摘要： In an ultra-wideband (“UWB”) network, a central location engine (“CLE”) coordinates operation of an anchor access point (“AP”), AP[0], and a plurality of non-anchor AP[x]s. A clock calibration packet (“CCP”) transmission method and related apparatus facilitate normalization of CCP time references reported to the CLE by all APs. Implementing a digital phase locked loop (“DPLL”) in the CLE facilitates clock normalization. Implementing a DPLL in at least the non-anchor AP[x]s facilitates local clock synchronization, and may improve network efficiency by reducing clock synchronization traffic.
