    摘要： A mobile communication system and method for transmitting signals through a plurality of transmission antennas by space-time coding the signals. The signals are transmitted using a low density parity check code. A lifting low density parity check matrix is formed by expanding values of elements in a low density parity check matrix with a sub-matrix corresponding to a number of the transmission antennas. The signals to be transmitted are coded using the lifting low density parity check matrix. Thereafter, the coded signals are serial/parallel converted and transmitted through the transmission antennas.

    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.
