Abstract
In multi-user MIMO (MU-MIMO) downlink system, in order to reduce the complexity of the client processing, transmitter precoding design for multi-user MIMO system performance is very important. Precoding based on signal leakage noise ratio(SLNR) eliminates the co-channel interference (CCI) and noise to improve the system performance. Since the users that the base station server at the same time are limited, user scheduling based on maximum signal to noise ratio of the leakage can be a reasonable choice to improve the diversity gain, obtain higher system capacity and better system performance. Simulation results prove that the SLNR precoding is superior to the zero-forcing (ZF) precoding and maximizing each user's receiving signal to noise ratio (MRT) precoding. What's more, using SLNR precoding and maximum signal leakage noise ratio scheduling are much better than the round-robin scheduling and the maximum channel gain scheduling. With the increase of users to be selected, it has little effect on the system scheduling strategy.关键词
