Abstract:
1. A communication system comprising a transmission device and a reception device, wherein the transmission device comprises: multiple transmission antennas; and a transmission unit which transmits multiple transmission signals from the multiple transmission antennas to the reception device, and the reception device comprises: at least one reception antenna which receives the multiple transmission signals transmitted by the transmission unit; a propagation channel response estimation unit which estimates propagation channel responses among the multiple transmission antennas and the reception antenna; a block division unit which divides a reception signal of at least one of the reception antennas into multiple blocks based on a multipath; and a transmission signal detection unit which detects the transmission signals transmitted by the transmission device based on the reception signal divided by the block division unit into the multiple blocks and the propagation channel responses estimated by the propagation channel response estimation unit, wherein the transmission signal detection unit comprises: an interference cancellation unit which generates and removes an interference replica; and a signal separation unit which separates a signal into which a transmission signal is multiplexed from an output of the interference cancellation unit.
