An RF unit receives multicarrier signals via a plurality of antennas. A division unit divides the multicarrier signals received into a plurality of groups in the frequency domain. The division unit acquires the channel quality for each subcarrier, contained in the multicarrier signal, in the frequency domain, and defines the plurality of groups according to the channel quality. The processing unit performs adaptive array signal processing for each of the divided groups.
