Included are a demodulation unit that demodulates a received OFDM modulation signal to acquire a demodulated constellation signal, an ideal constellation signal generation unit that generates an ideal constellation signal from the demodulated constellation signal, a data extraction unit that extracts signal data corresponding to subcarriers included in a part of an intermediate frequency section among all frequency sections, from the demodulated constellation signal and the ideal constellation signal, a phase error calculation unit that calculates the phase error of the demodulated constellation signal for the ideal constellation signal, with respect to the extracted signal data, a phase error characteristic estimation unit that estimates the frequency characteristic of the phase error, and a phase error correction unit that corrects the phase error of the demodulated constellation signal, based on the frequency characteristic of the phase error.
