Synchronization part 101 guard correlation balance station specifies on the basis of guard correlation value, calculates carrier direction shift quantity Fshift. As for equalization section 102, just the carrier direction shift quantity Fshift which was calculated in synchronization part 101, pass band of the carrier interpolation filter in carrier interpolation section 111 is made to shift. Delay profile means to be settled on the center of pass band of the carrier interpolation filter with this shift processing, vis-a-vis each FFT window position. Depending, when pass band of the carrier interpolation filter it is narrow from guard period, transmission line presumption becomes possible without adding restriction to the range of FFT window position.
