Abstract:
1. A transmission device including a plurality of transmission antennas and configured to spatially multiplex and transmit a plurality of signals addressed to a plurality of reception devices, the transmission device comprising: a multiplexed signal generator configured to determine whether to set each one of the plurality of reception devices to be a first reception device or a second reception device, a power suppression process of suppressing a power of a transmission signal from which an interference is cancelled being performed for the first reception device, the power suppression process being not performed for the second reception device, the multiplexed signal generator being configured to generate a multiplexed signal by multiplexing signals addressed to the plurality of reception devices, a first signal of the signals which is addressed to the first reception device having been subjected to the power suppression process, and a second signal of the signals which is addressed to the second reception device being not subjected to the power suppression process, wherein the multiplexed signal generator comprises: a modulo switch determining unit configured to determine whether to set each one of the plurality of reception devices to be the first reception device or the second reception device and to generate and output first transmission mode information that specifies the first reception device and second transmission mode information that specifies the second reception device; and an adaptive modulo unit configured to generate the first and second signals based on the first and second transmission mode informations received from the modulo switch determining unit.
