中文摘要：
针对多用户MIMO（Multiple—Input Multiple—Output）无线通信系统潜在的多用户分集增益，该文提出了一种基于一位反馈信息的多用户调度算法。理论分析表明，设置合理的门限可以从统计意义上最大化系统平均频谱效率。同时，该文从理论上对最优门限的选择进行了分析。仿真结果表明所提算法可有效利用多用户分集来提高系统的频谱性能。
英文摘要：
To exploit multi-user diversity for multi-user MIMO system, a scheduling algorithm is proposed based on one-bit feedback information in this paper. It is proved in this paper that the value of threshold is important for the system performance, and the problem how to select the optimum threshold for multi-user MIMO systems is solved through theoretical analysis. Simulation results show that the proposed scheme achieves good performance in terms of the average system spectral efficiency by exploiting the multiuser diversity.
