Abstract:
A reception device which communicates with a transmission device including multiple transmission antennas, the reception device including: at least one reception antenna which receives multiple transmission signals transmitted by the transmission device from the multiple transmission antennas; 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. The transmission signal detection unit includes: an interference cancellation unit and a signal separation unit.
