摘要

A receiver which allows suitable setting of the position of an FFT (Fast Fourier Transform) window (execution timing) when executing FFT to demodulate an OFDM (Orthogonal Frequency Division Multiplex) signal. The receiver estimates the transmission path property of a received OFDM signal and estimates an ISI (Inter Symbol Interference) amount in each case of a plurality of FFT window position candidates from the estimated transmission path property. An FFT window position candidate wherein the ISI amount is estimated to be the smallest among the FFT window position candidates is set as an actual FFT window position, and executes Fourier transformation.
