Abstract:
When transmitting signals from a plurality of base stations (broadcasting stations), the base stations include at least a first base station having a first antenna with a first polarization and a second base station having a second antenna with a second polarization that is different from the first polarization. Then, when the first base station transmits a signal from the first antenna having the first polarization, the second base station transmits the same signal as the first antenna of the first base station from a second antenna having the second polarization, at the same time.

Claim (Index 5):
A transmission method executed by a first base station and a second base station, the transmission method comprising:\n generating a first baseband symbol and second baseband symbol from transmission data; generating a first pilot symbol and a second pilot symbol; generating a first transmission signal including a first data symbol and a third pilot symbol, the first data symbol being the same as a result of applying a second phase changing process to the first baseband symbol, and the third pilot symbol being the same as a result of applying the second phase changing process to the first pilot symbol; generating a second transmission signal including a second data symbol and a fourth pilot symbol, the second data symbol being the same as a result of applying a first phase changing process and the second phase changing process to the second baseband symbol, and the fourth pilot symbol being the same as a result of applying the second phase changing process to the second pilot symbol; generating a third transmission signal including a third data symbol and a fifth pilot symbol, the third data symbol being the same as a result of applying a third phase changing process to the first baseband symbol, and the fifth pilot symbol being the same as a result of applying the third phase changing process to the first pilot symbol; generating a fourth transmission signal including a fourth data symbol and a sixth pilot symbol, the fourth data symbol being the same as a result of applying the first phase changing process and the third phase changing process to the second baseband symbol, and the sixth pilot symbol being the same as a result of applying the third phase changing process to the second pilot symbol; transmitting the first transmission signal and the second transmission signal by using a plurality of antennas of the first base station; and transmitting the third transmission signal and the fourth transmission signal by using a plurality of antennas of the second base station, wherein the first transmission signal, the second transmission signal, the third transmission signal, and the fourth transmission signal are transmitted simultaneously at same frequency.
