TRANSMISSION DEVICE, RECEPTION DEVICE, AND SIGNAL TRANSMISSION METHOD

摘要

This system has a plurality of transmission stations (14-1, 14-2) as transmission stations having a plurality of antennas, and is able to adopt a first method and a second method, wherein a transmission device (1), which generates a signal to be transmitted from the plurality of transmission stations to a reception device (2), is provided with a transmission unit that transmits to the reception device a control signal containing information indicating which method of the first method and second method is to be adopted, the first method being a method of performing spatio-temporal encoding using a plurality of antennas provided to different transmission stations, and performing space division multiplexing using the plurality of antennas provided respectively to the plurality of transmission stations, and the second method being a method of performing space division multiplexing using the plurality of antennas provided respectively to the plurality of transmission stations without performing spatio-temporal encoding using the plurality of antennas provided to different transmission stations.
