摘要

A transmission method for simultaneously transmitting a first modulated signal and a second modulated signal at the same frequency, comprising the steps of precoding using both a fixed precoding matrix and a phase of at least one phase of a first modulated signal or a second modulated signal, Are regularly switched and transmitted, thereby improving the reception quality of data in the receiving apparatus.;
