TRANSMISSION APPARATUS AND TRANSMISSION METHOD USING A PLURALITY OF DIVIDED FREQUENCY BANDS IN A COMMUNICATION BAND

摘要

A radio communication apparatus capable of alleviating a burden in setting a transmission format and suppressing increases in the scale of the apparatus. In this apparatus, space multiplexing adaptability detection section detects space multiplexing transmission adaptability for divided bands obtained by dividing a communication band to which Ns subcarrier signals belong in multicarrier transmission and to which a plurality of subcarrier signals belong, and outputs the detection results. Transmission format setting section sets a transmission format when carrying out radio transmission based on the detection results from space multiplexing adaptability detection section.
