摘要：
In a multiple-antenna system, the transmit power allocation over different sub-channels is an effective means to improve the performance. In this paper, the optimal transmit power allocation scheme is first introduced, and then a novel power allocation scheme is derived. Simulation results show that the new proposed scheme can provide high channel capacity similar to the optimum power allocation scheme in the condition of low SNR. And our proposed scheme has the lower computation complexity than the latter.
