QoS based optimization of multi-user selection with criterion of SLNR

As a resolve to high complexity of user selection and different users with different requirements of QoS(Quality of Services) optimization of multi-user selection with criterion of SLNR based on QoS is proposed in this paper with maximization of SLNR(Signal-to-leakage and Noises Ratio) as standard and different settlements of scheduling for different kinds of users in MIMO (Multiple-input multiple-Output) system. The simulation compares this algorithm with round robin scheduling and leakage based user scheduling. The results show the proposed optimization is much better not only in channel capacity but also in throughput and BER (Bit error rate) than these two algorithms.
