摘要
To enhance the sum rate of maximising the signal-to-leakage-and-noise ratio (Max-SLNR), a signal-to-interference-and-noise ratio (SINR) based power allocation (PA) is proposed for Max-SLNR per substream of users in multiuser MIMO systems. Simulation shows that the rate gain of SINR based PA over equal PA is about 0.5bit/s/Hz per user at low and medium signal-to-noise ratios in the presence of shadow fading and antenna correlation.
