Abstract
In-phase channels and quadrature-phase channels of carrier waves are calculated from a reception signal obtained by receiving the multi-carrier signal. Transmission channel characteristics of the carrier waves are calculated from a known signal section of the reception signal. Transmission channel equalization processing for compensating for an amplitude change and phase rotation in the in-phase channels and the quadrature-phase channels caused by a transmission channel is performed. A region on a complex plane in which output data after transmission channel equalization is present is determined. An estimation value of a phase rotation angle used in performing the transmission channel equalization processing is corrected based on information concerning the determined region.
