Patent ID: 8150326

Claim:
A signal processing method in a base station receiver that receives and processes single carrier or multiple carrier signals from a plurality of transmitting units in a sectored coverage area, signal power gain between transmit and receive antennas of one or more transmitting units and the receiver within each sector being represented as a channel matrix with path gains, the method comprising: determining if signal from a given target transmitting unit is available in the received signal of a sector; in case the signal from the target transmitting unit is detected in at least two sectors, combining a plurality of the channel matrices associated with respective ones of the at least two sectors to generate a channel matrix which is larger in size than each of the channel matrices associated with the respective sectors, and concatenating a plurality of received signal vectors associated with the respective sectors to generate a received signal vector which is larger in size than each of the received signal vectors associated with the respective sectors; and canceling interference from one or more other transmitting units sharing a given channel with the target transmitting unit, using the generated channel matrix and the generated received signal vector; while in case the signal from the target transmitting unit is detected in only one sector, canceling interference from the received signal from the transmitting unit, using the channel matrix and the received signal vector each associated with the one sector.
