PROBLEM TO BE SOLVED: To efficiently detect a synchronous position of a received signal.SOLUTION: A selection signal generation unit 102 generates a plurality of selection signals indicating signal sequences to be selected. A first selection unit selects received digital element signals corresponding to the signal sequences indicated by each of the plurality of selection signals from one received digital signal. A first signal generation unit 104 demodulates the received digital element signals selected by each of the plurality of selection signals to generate a plurality of first signal. A known signal generation unit 102 generates a known signal. A second selection unit 106 selects the known element signals corresponding to the signal sequences indicated by each of the plurality of selection signals from the known signal. A second signal generation unit 107 demodulates the known element signals selected by each of the plurality of selection signals to generate a plurality of second signals. A synchronous processing unit 108 compares the first signals and second signals generated corresponding to each of the plurality of selection signals to detect a synchronous position. |
