Patent ID: 7453949

Claim:
A receiver for receiving M multi-carrier signals transmitted from M transmit antennas, M>1, the receiver comprising: at least (M+1) receive paths, each receive path adapted to receive the M multi-carrier signals and separate the received signals into separate subcarrier signals; and a processor adapted to process the separate subcarrier signals to generate a recovered version of each of the M transmitted multi-carrier signals, wherein the processor comprises: a first processing block adapted to receive the separate subcarrier signals from each receive path and to generate M first signals, each first signal containing (1) desired signal corresponding to one of the transmit antennas and (2) interference; a second processing block adapted to receive the separate subcarrier signals from each receive path and to generate a second signal representative of the interference in the M first signals; and an interference cancellation block adapted to combine each first signal with a portion of the second signal to generate a recovered signal having less interference than said each first signal.
