To reduce an error rate of received data, a MIMO processing unit (202) receives data transmitted from a transmitter via antennas (201-0 to 201-3) and separates packets of layers 0 to 3 transmitted from respective antennas of the transmitter. Maximal ratio combining units (203-0 to 203-3) perform maximal ratio combining on duplicate portions of packets of the layers 0 to 3. Turbo decoding units (204-0 to 204-3) perform turbo decoding on packets of the layers 0 to 3 in which respective duplicate portions are maximal-ratio-combined. A soft-decision value combining unit (205) combines soft-decision values for respective information bits of the layers 0 to 3 obtained as a result of turbo decoding on packets of the layers 0 to 3 by the turbo decoding units (204-0 to 204-3). A hard-decision unit (206) obtains hard-decision values corresponding to respective information bits of the layers 0 to 3 in the transmitter. |
