An OFDM reception apparatus for receiving and demodulating an OFDM signal comprising a fast Fourier transform section for converting a received OFDM signal into a frequency-domain OFDM signal, a channel response calculation section for obtaining a channel response with respect to a carrier transmitting a pilot signal, from the frequency-domain OFDM signal, an interpolation section for interpolating the channel response, and outputting the result, a power calculation section for calculating the square of a magnitude of the interpolated channel response, as a carrier power, for each carrier corresponding to the channel response, an interference calculation section for calculating a degree of an influence of interference on the received OFDM signal, as an interference power, for each carrier corresponding to the interpolated channel response, and a carrier quality calculation section for calculating a ratio of the carrier power obtained to the interference power corresponding thereto, for each carrier.
