PROBLEM TO BE SOLVED: To provide a transmission method to simultaneously transmit plural modulated signals from plural antennas, capable of improving the reception quality under circumstances in which a direct wave is dominant.SOLUTION: The precoding method is a transmission method for simultaneously transmitting a first modulated signal and a second modulated signal with an identical frequency. In the precoding method, a first mapped base band signal and a second mapped base band signal are multiplied by a precoding weight. A precoding weight multiplication section which outputs the first modulated signal and the second modulated signal regularly changes the precoding weight.
