To enhance the sum rate of maximizing signal-to-leakage-and-noise ratio (Max-SLNR) in the downlink multi-user multiple-input multiple-output (MU-MIMO) system, we propose an iterative power allocation scheme. Compared with conventional power allocation schemes, the proposed scheme achieves higher system throughput. Numerical results show that the complexity of the scheme is reduced by decreasing the number of iteration without losing system throughput.
Key words： MU-MIMO; SLNR; power allocation; iterative
