Abstract
A radio transmission apparatus includes a plurality of antennas each having an amplifier, a transmission signal generation unit (modulation units, S/P units, and FFT units) which generates a signal to be transmitted to a terminal via the antennas, and a weighting processing unit (a precoder unit, a maximum power calculation unit, and multipliers) which executes a weighting process on a signal to be transmitted to the terminal, which has been generated by the transmission signal generation unit, based on channel state information between the radio transmission apparatus and the terminal and an output limit value of the amplifier.
