Zusammenfassung:Output terminal 340 extracts specific subcarrier data assigned by a base station from at least one of a plurality of butterfly operation sections provided in output terminal 340. The butterfly operation sections in first node 320, second node 330, and output terminal 340 make only butterfly operation sections relating to extraction of the specific subcarrier data perform the butterfly operation. Thereby, unnecessary butterfly operation performed in butterfly operation unit 300 is omitted.
