摘要：
Multiple-input and multiple-output (MIMO) system has captured considerably attention recently. In this paper, we present the analysis of multiuser scheduling in MIMO Space-Time Block Coding (STBC) system with imperfect channel estimation. Three commonly used multiuser scheduling methods - max throughput, round robin (RR) and proportional fair (PF) - are implemented to the MIMO STBC system and their performances are analyzed with imperfect channel estimation. Numerical and simulation results are provided to show multiuser diversity and the impact of imperfect channel estimation on the multiuser scheduling performance in MIMO STBC systems. The simulation results show that more multiuser diversity gain is obtained as the increase of user number and the channel estimation errors has a great impact on the performance of max throughput and PF methods.
