摘要： In each Mobile terminal, channel impulse characteristics from radio base stations to the mobile terminal is calculated. In a radio communication system, under the assumption that each of the mobile terminals performs optimum receiving beamforming in order to receive a data signal from a radio base station that actually sends the data signal to the mobile terminal, optimum receiving beamforming characteristics are estimated for each mobile terminal. Each of radio base stations that share optimum receiving beamforming characteristics calculates precoding characteristics for each mobile terminal according to the optimum receiving beamforming characteristics such that main beams are directed to mobile terminals to which the radio base station sends data signals and null beams are directed to mobile terminals to which the radio base station does not send data signals.
