Multiplier 103 calculates the correlation value of the received signal with the one-symbol-delayed received signal, integrator 104 integrates the calculated correlation value, subtracter 105 executes subtract processing between the integrated value and an arbitrary threshold level, and decider 106 decides a level of the resultant, fastest timing detection section 107 compares the peak detected timing for each of a plurality of frames received during a predetermined time to each other to select the fastest peak detected timing, and using the selected timing as a processing initiation timing, FFT circuit 108 executes FFT processing on the received signal. <IMAGE>
