摘要:
Phase shift values between signals received at a plurality of receiving antennas are determined to orient one or more receiving antennas of the plurality of receiving antennas during signal location. Subsequent signals are received utilizing the oriented receiving antennas. Candidate angle of arrival (AOA) values are computed based on the determined phase shift values during the signal location so as to adaptively orient the receiving antennas. Each of the candidate AOA values is iteratively selected one at a time to adaptively orient the receiving antennas. The receiving antennas may be adaptively oriented according to the computed receive signal power levels. The determined phase shift values may be rounded to nearest discrete phase shift values. In this regard, one candidate AOA value is selected for each of the receiving antennas based on the corresponding rounded phase shift values such that the receiving antennas may be adaptively oriented during the signal location.
