| Abstract: | A new scheme in the correlated MIMO channel consisting of a combination of the space-time block code,the spatial multiplexing and the beamformingis presented.The proposed scheme exploits the benefits of the combining transmit diversity and the spatial multiplexing to provide the diversity and the multiplexing gain.Based on the correlation matrix of the channel,a beamformer is designed.The simulation result shows that this scheme is better in performance than the conventional scheme when the SNR is high. |
