Methods and apparatus are provided for determining a direction of arrival (DOA) (46) of a Radio Frequency (RF) signal (32) transmitted by a remote unit (22) in a wireless communication system (20). The methods comprise receiving the RF signal (32) with multiple antennas (34,36,38,40,42,44) of the antenna array (26) and determining a preliminary direction of arrival (DOA) (78) for the RF signal (32) received with the multiple of antennas (34,36,38,40,42,44) of the antenna array (26). The methods also comprise selecting a coefficient (80) for the antenna array (26) based at least in part upon the preliminary DOA 978), modifying the RF signal (32) with the coefficient (80) to generate a modified RF signal (82), and determining the DOA (46) of the RF signal (32) with the modified RF signal (82).
