Abstract:
1. A wireless reception device which communicates with a wireless transmission device which has a plurality of transmission antennas, the wireless reception device comprising: at least one reception antenna configured to receive a plurality of transmission signals transmitted from the plurality of transmission antennas of the wireless transmission device; a channel response estimation unit configured to estimate a channel response between the plurality of transmission antennas and the at least one reception antenna; a block dividing unit configured to divide a reception signal of the at least one reception antenna into a plurality of blocks, based on multi paths; a signal detection unit configured to detect the plurality of transmission signals transmitted by the wireless transmission device based on the reception signal corresponding to the plurality of blocks divided by the block dividing unit and the channel response estimated by the channel response estimation unit, and to calculate a bit likelihood based on the reception signal received by the at least one reception antenna; and a reception replica signal generation unit configured to generate a reception replica signal based on the channel response estimated by the channel response estimation unit and the bit likelihood calculated by the signal detection unit, wherein the block dividing unit divides the reception signal of the at least one reception antenna into the plurality of blocks using the reception replica signal generated by the reception replica generation unit.
