Abstract:
A radio communication apparatus for transmitting and receiving modulation signals of a plurality of channels in the same frequency band via a plurality of antennas. A communication method is based on information on electric wave propagation environment corresponding to each antenna of the communication partner and transmission is performed by selecting a transmission method for transmitting modulation signals of channels in the same frequency band from a plurality of antennas or a transmission method for transmitting a modulation signal of one channel from one antenna. Thus, it is possible to multiplex a plurality of modulation signals so as to be transmitted and to demultiplex and demodulate the transmitted multiplexed modulation signals at a reception unit, thereby improving the data transmission rate.
