PROBLEM TO BE SOLVED: To suppress deterioration of transmission characteristics of data while suppressing an increase of a processing amount. SOLUTION: An RF part 12 receives each signal constituted by a plurality of blocks, and a plurality of carriers are used to each of a plurality of the blocks with a plurality of antennas 10. A measurement part 24 measures quality of the received signals. A processor 16 executes adaptive array signal processing to the signals received with a plurality of the antennas 10, while changing the number of the carriers for standardizing weight in the adaptive array signal processing on the basis of the quality measured by the measurement part 24. Priority is imparted to each of a plurality of the blocks. The processor 16 reduces the number of the carriers for standardizing the weight in the adaptive array signal processing to the high-priority block rather than the low-priority block when the quality is deteriorated.
