摘要：A receiver and transmitter of a closed-loop MIMO antenna system using acodebook and a receiving and transmitting method thereof are provided. The receiver ofthe MIMO antenna system includes a window size decider and a beamforming weightselector. The window size decider stores a codebook with beamforming weights andselects the beamforming weights corresponding to a window size from the codebook,and the beamforming weight selector selects an optimal beamforming weight based on acurrent channel state among the beamforming weights outputted from the window sizedecider, and feeds back the selected optimal beamforming weight to a transmitter.
