Abstract  Abstract

A transmission method for transmitting modulation signals of a plurality of channels to the same frequency band from a plurality of antennas. At the time when a symbol used for demodulation is inserted in a channel in another channel symbol the same phase and quadrature signals in the in-phase-quadrature plane are made to be zero signals. Thus a plurality of modulation signals are multiplexed and transmitted and the transmitted multiplexed modulation signals are demultiplexed and demodulated at a reception apparatus thereby improving the data transmission rate.
