Space multiplex radio communication method and radio communication apparatus
A radio communication system is comprised of: a transmitting system in which N transmission signals, frequency-converted to the same transmission frequency, are generated by N transmitters, N being an integer equal to or greater than 2, and the transmission signals are each applied to each one of N elements of an antenna for transmission; and a receiving system in which each transmitted signal is received by N-element antenna and the cross correlation coefficient between the transmitted signals received by the N-elements is minimized to thereby reconstruct each transmitted signal. The plural transmitted signals of the same frequency are received and the cross correlation coefficients of the received transmitted signals are minimized to thereby permit multiplexing of the transmission signal.
