(English Abstract) |
In this paper, we propose a beamforming scheme that exploits the advantages of opportunistic beamforming and coherent beamforming in multi-user environments. It is analytically shown that the proposed scheme can provide multi-user diversity and beamforming gain simultaneously, achieving significant performance improvement over the conventional ones particularly when the channel is poor. The performance of the proposed scheme is analyzed using an upper bound method. Finally, the analytic results are verified by computer simulation.
