Abstract  Abstract

(PROBLEMS) To obtain maximum throughput in accordance with characteristic of the transmission path. (MEANS FOR SOLVING PROBLEMS) A radio transmission device includes a plurality of transmission antennas (18a 18b) and spatially multiplexes the transmission signal on sub-carrier unit or performing transmission without performing spatial multiplex. The radio transmission device includes a sub-carrier modulation unit (11) for modulating the inputted transmission signal for each sub-carrier a transmission signal division unit (13) for dividing the transmission signal modulated for each sub-carrier to each transmission antenna and a transmission control unit (12) for deciding the number of multiplexes for performing spatial multiplex for each sub-carrier according to the information received from another radio communication device as a communication partner and outputting the decided number of multiplexes to the sub-carrier modulation unit and to the transmission signal division unit.
