The present invention provides an apparatus and a method that realize dynamically processing signals received from multiple sectors to increase throughput of uplink communications in a multi-sectored wireless base station. The signal streams received from sector-1 (25) and (26) and signal streams received from sector-2 (27) and (28) are concentrated in a unit (105). Similarly, channel parameters (29) and (30) from sector-1 and sector-2, respectively, are used to create a modified channel matrix, dimension of which is much larger than that of each of channel matrices of respective sectors. Dynamic processing of signals received from multiple sectors is done by a detection unit (103) which receive channel parameters (131) or (133), and, a comparison unit (104). Signals from a transmitting unit are detected within the signals received from two or more sectors, or the same signals are detected within the signal received from one sector. Based on the results of the comparison unit (104), a modified channel matrix and received signal vector from one sector is selected in a channel matrix selection unit (102) and used in a unit (21) to perform interference cancellation.
