CDMA location using multiple antennas and interference cancellation

Location finding for CDMA subscribers using an antenna array at the base station and deploying multiple base stations is studied in this paper. Two methods are considered for radio location: measured time-of-arrival (TOA) and angle-of-arrival (AOA), and algorithms to estimate them are presented. The estimated TOA and AOA from different base stations are combined via data fusion to estimate the user's interference location by exploiting the topology of the cellular network.
