Transmission method, transmission apparatus, and reception apparatus

摘要

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 demodulation symbol (101) is inserted in a channel, in another channel symbol (109), 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.
