An FFT unit subjects a baseband signal to FFT operation. An IQ-to-phase conversion unit converts an in-phase component value and a quadrature component value of each of a plurality of signals on respective subcarriers subjected to FFT into a phase component value. A phase equalization unit generates a plurality of reference phase values, based on the phase component of each of the plurality of signals on the respective carriers. Further, the phase equalization unit rotates the phase components of the signals on the respective carriers, in accordance with the plurality of reference phase values. A phase correction unit estimates an error in the phase component value of each of the plurality of signals on the respective carriers, based on a phase component of a pilot signal. Further, the phase correction unit rotates the phase component value of each of the plurality of signals on the respective subcarriers for a second time.
