Abstract
A receiver is disclosed. The receiver includes one or more antennas receiving signals from a transmitter including one or more antennas, and at least one RF chain generating digital samples based on the received signals. Either A) the signals are transmitted by a single antenna of the transmitter and are received by multiple antennas of the receiver, or B) the signals are transmitted by multiple antennas of the transmitter and are received by a single antenna of the receiver. The receiver also includes a controller determining a plurality of groups of digital samples to use for calculating estimates of an AoA or AoD of the received signals, calculate estimates of AoA or AoD based on the groups of digital samples, select a subset of the estimates, and calculate a measured AoA or AoD based on the selected subset of estimates.
