A reception device (1) has reception antennas (11-1 to 11-n) for receiving signals transmitted from a plurality of transmission antennas and outputting reception signals. A channel estimation device (12) estimates a channel between the antennas and outputs a channel estimation value H. A path selection device (13) inputs the channel estimation value H and calculates the channel correlation value between the transmission/reception antennas from the channel estimation value H. If the calculation result is smaller than a reference value, the path selection device (13) outputs a path selection signal selecting a path of a high power with a higher priority. On the other hand, if the calculation result is greater than the reference value, the path selection device (13) outputs a path selection signal selecting, with a higher priority, a path having a lower correlation value with a path detected by the other reception antenna. Despread devices (14-1 to 14-kn) input the reception signal and the path selection signal and output a despread signal. A demodulation device (15) inputs a despread signal and outputs a reproduction series. |
