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： A method of synchronizing signals is disclosed. The method comprises using a clock tracking system to convert a future event target time specified in a time base of a master device into the local unsynchronized time bases of one or more slave devices. Each of the slave devices then generates an event signal at the converted time, such that a coordinated delivery of synchronized signals is achieved.
