MIMO Adaptive Perturbation-aided Opportunistic Beamforming method and MIMO system using the same

摘要

The present invention relates to a transmission beamforming technique of a multi-antenna system, in an opportunistic beamforming using only limited channel information after beamforming at random, BS without requiring additional information exchange or change in MS hardware design between the BS and the MS It has the advantage of improving the data transfer rate through minor modification of the additional memory part and the decision block in the scheduler.
