An OFDM receiver includes: OFDM-signal receiving means (10) for receiving an orthogonal frequency division multiplexing (OFDM) signal; channel-characteristic estimating means (17) for estimating a channel characteristic using pilot signals in the OFDM signal received by the OFDM-signal receiving means (10); and transmission-distortion compensating means (18) for applying, on the basis of the channel characteristic estimated by the channel-characteristic estimating means (17), processing for compensating for transmission distortion to the OFDM signal received by the OFDM-signal receiving means (10). The channel-characteristic estimating means (17) includes: plural kinds of time-direction-channel estimating means (172) used for the estimation of a channel characteristic; and switching control means for switching these estimating means (172) according to a state of a channel.
