Abstract  Abstract

PROBLEM TO BE SOLVED: To improve a data transmission rate by multiplexing and transmitting a plurality of modulation signals in a transmitting apparatus and demultiplexing and demodulating the transmitted multiplexed modulation signals in a receiving apparatus.

SOLUTION: In a transmission method for transmitting the modulation signals of a plurality of channels to the same frequency band from a plurality of antennas when a demodulation symbol 101 is inserted in a channel in another channel symbol 109 the same phase and orthogonal signals in the in-phase-quadrature phase plane are made to be zero signals. Thus the plurality of modulation signals are multiplexed and transmitted and the transmitted multiplexed modulation signals are demultiplexed and demodulated at the receiving apparatus thereby improving the data transmission rate.
