Abstract :
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.
