In the downlink of multiuser MIMO (MU-MIMO) systems, the co-channel interference (CCI) and noise are two major impairments. Maximizing signal to leakage plus noise ratio (SLNR) is a good criterion for the design of precoders since it making a balance between eliminating the CCI and noise. In this text, we propose a channel adaptive power allocation scheme based on SLNR precoding. Simulation results show that the proposed scheme can improve the BER performance considerably with a minor loss in the sum capacity performance. And we also illustrate that the additional computational complexity is very small.
