A delay equalizing unit includes a delay time calculating unit for calculating a plurality of delay times which differ from each other by short time periods and which include the delay time of the delayed wave with respect to the direct wave, so that an OFDM-modulated signal input to path correlation detectors is delayed by the plurality of delay times. A feedback unit causes the amplitude and phase of the negatively fed back direct wave to coincide with the amplitude and phase of the delayed wave input to an adding unit based on the largest of the path correlations, so that the negatively fed back direct wave is delayed by a designated delay time based on which the largest path correlation is determined.
