Abstract
A method and device using a single transmitter (TX) and/or a single receiver (RX) is provided for determining an angle measurement between the transmitter and receiver for an ultra-wideband (UWB) system. A plurality of RX antennas is coupled to the receiver and a plurality of TX antennas is coupled to the transmitter. An IEEE 802.15.4z standard provides a silent period or gap before and after scrambled timestamp sequences (STS) in a frame. An active antenna is switched to a different antenna in the gaps. This allows the angle measurements to be performed with only a single transmitter and receiver within one channel impulse response (CIR) measurement cycle.
