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).
