Abstract
A correction unit corrects the phases of received multicarrier signals, respectively, carrier by carrier. A combining unit and a computing unit performs adaptive array processing on the corrected multicarrier signals on a carrier-by-carrier basis. A derivation unit derives, carrier by carrier, a phase for correction to be used by the correction unit, based on error in the multicarrier signals which have undergone the adaptive array processing. The derivation unit updates a frequency for correction about a carrier to which a known signal is assigned, based on error in the carrier, so as to derive a phase for correction and the derivation unit also derives a phase for correction, based on the error in the carrier and the phase for correction in a carrier to which the known signal is assigned.
