SIGNAL GENERATION METHOD AND SIGNAL GENERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To improve estimation accuracy of a channel estimation in a receiving device.SOLUTION: Weighting composition of first and second baseband signals is performed in accordance with a prescribed matrix F. Power change is applied to resultant first and second weighted composite signals, phase change is applied to at least one of the first and second signals after power change, the first and second signals after power change to at least one of which phase change is applied is transmitted by first and second antennas of the same frequency and at the same time of day, and first and second pilot signals transmitted by the first and second antennas of the same frequency and at the same time of day are generated. A ratio of an average power of the first signal after power change to an average power of the second signal after power change differs from a ratio of an average power of the first pilot signal to an average power of the second pilot signal.
