Beamforming method for a MIMO space division multilplexing system

摘要

A beamforming method in a communication system having a transmitter for transmitting signals to users on a plurality of transmit antennas, and spatially identifying the users and a plurality of receivers for receiving the signals discriminately. A beamforming weight is determined based on channel information received from each of the receivers, based on whether the each receiver uses a single antenna or a plurality of antennas. A transmission signal is multiplied by the beamforming weight and transmitted. <IMAGE> <IMAGE>
