A method and apparatus for interference cancellation in wireless receivers

Abstract

A method and apparatus for a multi-branch wireless receiver for periodically sampling first and second received signals corresponding to first and second receiver branches at first and second sample times to generate offset sample streams. The offset sample streams are then combined in a combining circuit to reduce interference present in the received signals. In an exemplary embodiment, a multi-branch wireless receiver includes an offset circuit to generate first and second offset sample times. A first sampler periodically samples the first received signal at the first sample time to generate a first sample stream and a second sampler periodically samples the second received signal at the second sample time to generate a second sample stream offset from the first sample stream. The combining circuit comprises a RAKE receiver that reduces the interference by scaling and combining despread values generated from the offset sample streams.
