Claim:
1. A signal generation method for generating, from a plurality of baseband signals, a plurality of signals for transmission on a same frequency band and at a same time, comprising the steps of: applying a phase change to a first baseband signal generated from a first set of bits and a second baseband signal generated from a second set of bits; and applying a precoding to the first baseband signal and the second baseband signal according to a predetermined matrix F, wherein the phase change is continually applied to the first baseband signal and the second baseband signal using a phase change value sequentially selected from among N phase change values, N being an integer greater than two and greater than the number of baseband signals, and each of the N phase change values being selected at least once within a predetermined period, and a difference between two adjacent phase change values of the N phase change values is 2π/N.
