Signal to Leakage and Noise Ratio Based Beamforming and User Scheduling for TD-LTE-A Systems

摘要：

　　In TD-LTE-A downlink,signal to leakage and noise ratio (SLNR) based beamforming can eliminate the co-channel interference and noise for multi-user MIMO mode effectively and can be realized more easily than the traditional ideal SINR based algorithms.Moreover,user scheduling can be combined with the SLNR based beamforming algorithm to obtain a better performance.Hence,in this paper,SLNR based beamforming is firstly compared with traditional beamforming algorithms,and then,a suboptimal maximum minimum SLNR (MMSLNR) scheduling strategy is proposed to improve the average BER performance and sum capacity of TD-LTE-A system and decrease the scheduling complexity as well.
