Abstract
Each gain control amplifier 3 adjusts the transmission power of the transmit signals directed to each user according to the power control signal. Gaussian noise generator 4 generates Gaussian noise. Noise power control section 6 controls gain control amplifier 5 based on the power control signal to each user and total power control signal and adjusts the transmission power of the Gaussian noise so that the summation of the transmission power may be kept constant.
