Abstract  Abstract

PROBLEM TO BE SOLVED: To obtain the maximum throughput according to the characteristics of a propagation path. SOLUTION: A wireless transmission device that includes a plurality of transmission antennas (18a, 18b) and spatially multiplexes transmission signals in subcarrier units, or transmits without spatial multiplexing, in which input transmission signals are subcarriers. A subcarrier modulation unit 11 that modulates each subcarrier, a transmission signal distribution unit 13 that distributes the transmission signal modulated for each subcarrier to each transmission antenna, and another wireless communication device that is a communication partner are received. A transmission control unit 12 that determines the number of multiplexed signals to be spatially multiplexed for each subcarrier based on the information and outputs the determined number of multiplexed signals to the subcarrier modulation unit and the transmission signal distribution unit.
