PROBLEM TO BE SOLVED: To improve the transmission rate of data, by multiplexing and transmitting a plurality of modulated signals at a transmitter and by separating and demodulating the transmitted multiplexed modulated signals at a receiver.SOLUTION: In a transmission method for transmitting modulated signals at a plurality of channels in a same frequency band from a plurality of antennas, an in-phase signal and a quadrature signal in an in-phase/quadrature plane are signals of zero for a symbol 109 of other channels at a time when a symbol 101 for demodulation is inserted in a certain channel. Thereby, a plurality of modulated signals can be multiplexed and transmitted, and, at a receiver, the transmitted multiplexed modulated signals can be separated and demodulated. Accordingly, the transmission rate of data can be improved. |
