Abstract: A method is provided for estimating a signal's angle of arrival (AOA) in a communications system. Starting values for each of a horizontal AOA and a vertical AOA are estimated. The estimated vertical AOA starting value is used to select a horizontal PDOA trace of horizontal PDOA calibration data. The selected horizontal PDOA trace is interpolated to determine a best horizontal AOA estimate for a current iteration. The estimated horizontal AOA starting value is used to select a vertical PDOA trace of vertical PDOA calibration data. The selected vertical PDOA trace is interpolated to determine a best vertical AOA estimate for the current iteration. After each iteration, determining if a maximum number of iterations has been reached or if the best horizontal or vertical AOA estimate has not changed by a predetermined amount. When one of these is true, the best horizontal and vertical AOA estimates are used.

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.
