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.
