Abstract
A transmitting apparatus includes a subset matrix setting unit to set a subset matrix corresponding to a channel matrix with respect to each of a plurality of antennas of at least one of a plurality of user terminals, using channel matrices fed back from the plurality of user terminals; a beamforming matrix calculator to perform a predetermined operation using the set subset matrix so as to calculate a beamforming matrix composed of weight vectors respectively corresponding to the plurality of antennas of each of the plurality of user terminals; a beamforming processor to perform a beamforming process on data to be transmitted according to the calculated beamforming matrix so as to generate a transmission signal; and antennas to transmit the transmission signal to the plurality of user terminals. The transmitting apparatus obtains a diversity effect while removing interference between user terminals with a small quantity of computations.
