In the research on multi-user selection of Multiple Input Multiple Output (MIMO) broadcast system with limited feedback errors in users SINR estimation in existing methods are big, which constrains the system capacity. In this paper by combining the deduced upper and lower bound to estimate the users received signal power, a novel users SINR estimation method with smaller error is derived and a new corresponding multi-user selection algorithm is proposed. Simulation results show that better performance and lower complexity can be achieved with the proposed algorithm both in low SNR and in high SNR.
