A method and apparatus are provided for separating signals from a received combined signal in a wireless communication system. Combined signals are received by one or more antennas, demodulated and filtered. The combined signals are mixed with known scrambling codes of a target sector and possibly interfering sectors prior to signal separation, by which a separation matrix is created. The separation matrix is used to provide separate desired and interferer signals, such that the desired signals may be despread with known spreading codes for further decoder processing. In an alternate embodiment, the separation matrix is split according to scrambling and spreading code processing to decrease processing complexity. Feedback adjustment control may be used to adjust separation parameters based on generated separation matrices and separated signals.
