APPARATUS AND METHOD FOR BEAMFORMING BASED ON GENERALIZED EIGEN ANALYSIS IN A MULTIPLE INPUT MULTIPLE OUTPUT WIRELESS COMMUNICATION SYSTEM

摘要

present invention multiple-input multiple-output (MIMO: Multiple Input Multiple Output) wireless communication system in the beamforming (beamforming) relates to the base station, the terminal of each of the channel information for use by the terminal of the beamforming vectors and the creation of inter-relation, generalized eigen analysis (generalized eigen analysis) to be used for the relationship from the respective nodes of the beam-forming vector calculating the candidates, and the candidates of the beamforming vector calculated by the terminal for selecting the beamforming vector tile, which is only transmitted to each terminal by using the terminal-specific beamforming vector pilots (dedicated pilot) symbols forming a transmission beam for the including a plurality of transmit beamformer (beamformer) to perform, through the generalized eigen analysis (generalized eigen-analisys) determining a transmission beamforming vector, and by determining the receive beamforming vector by estimating the effective channel matrix, the terminal may perform the multi-user multiple-input multiple-output communication without interferences.
