Abstract
A robust joint multiuser scheduling and precoding design is proposed for uplink multiuser MIMO systems with imperfect channel state information (CSI). The effect of the antenna correlations is involved in the channel model. The multiuser scheduling and the precoding that avail the total mean square error (TMSE) minimization criteria under individual power constraint are firstly deduced and the combination of the two parts is designed in the following. The proposed design is compared with the robust precoding with random scheduling scheme and the non-robust scheme. The simulation results show that the joint design helps achieving larger system throughput and the robust algorithm mitigates the performance loss due to the imperfect CSI.
