<p>Provided is a transmission device for transmitting signals which are different for each of a plurality of reception devices, which has a filter calculation unit for calculating a prerecording filter corresponding to an equivalent propagation path matrix in which a propagation path matrix of a reception device has been quasi-orthogonalized, a prerecording unit for calculating a signal in which signals addressed to the reception device have been multiplexed on the basis of the calculated prerecording filter, and a transmission unit for transmitting the multiplexed signal. As a result, increase in transmit power of a base station device when removing all MUI in MU-MIMO LP, or a portion of the MUI in MU-MIMO THP, respectively, with a linear filter is suppressed.</p> |
