An OFDM receiver may include OFDM-signal receiving means for receiving an orthogonal frequency division multiplexing signal, channel-characteristic estimating means for estimating a channel characteristic, time-direction-channel estimating means used for the estimation of a channel characteristic, judging means for judging a result of the estimation of a time direction channel, switching control means for switching presence or absence of the estimation of a time direction channel in accordance with a result of the judgment on the result of the estimation of a time direction channel, and transmission-distortion compensating means for applying processing for compensating for transmission distortion to the OFDM frequency domain signal received by the OFDM-signal receiving means and subjected to the Fast Fourier Transform.
