Abstract
In this paper, we propose a beamforming scheme that
exploits the advantages of opportunistic beamforming and
coherent beamforming in multi-user environment. It is
analytically shown that the proposed scheme achieves multiuser
diversity gain and beamforming gain simultaneously,
providing much better performance over the conventional ones.
The performance of the proposed scheme is analyzed using an
upper bound method. Although the proposed scheme involves
an additional feedback delay, the analytical result implies that
the use of the proposed scheme is quite effective unless the user
mobility is too high. Finally, the analytic results are verified by
computer simulation.
