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