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 8):
A receiving apparatus comprising:\n an input that, in operation, obtains a received signal including a first transmission signal, a second transmission signal, a third transmission signal, and a fourth transmission signal that are transmitted simultaneously at a first frequency, the first transmission signal and the second transmission signal being transmitted from a first base station by using a plurality of transmission antennas of the first base station, the third transmission signal and the fourth transmission signal transmitted from a second base station by using a plurality of transmission antennas of the second base station, the 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 a first baseband symbol, and the third pilot symbol being the same as a result of applying the second phase changing process to a first pilot symbol, the 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 a second baseband symbol, and the fourth pilot symbol being the same as a result of applying the second phase changing process to a second pilot symbol, the 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, the 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, the receiving apparatus further comprising a demodulator that, in operation, demodulates the received signal by using a known value of the first pilot symbol and a known value of the second pilot symbol and a phase change amount used in the first phase changing process.
