Abstract :
In multiuser MIMO downlink link, maximizing signal to leakage and noise ratio (SLNR) is a good criterion for the design of precoders. In this text, we consider a user scheduling scheme based on this novel criterion. By replacing the WORST user with a Better one again and again according to the proposed updating scheme, we can keep the minimum SLNR of the scheduling users set as large as possible. Simulation results show that the proposed scheme can improve the system performance dramatically.
