摘要 对两种基于有限反馈的多用户MIMO系统用户调度方案进行对比分析。两种调度算法均仅反馈1bit CSI,其不同之处是方法一中基站仅根据瞬时CSI随机调度用户,方法二中基站通过瞬时CSI结合空间相关信息来调度用户。先从算法实现过程对两个方案进行分析,再从空间相关性的利用、同时可通信的用户数和系统容量对两个方案的优缺点进行比较。 Two limited feedback-based scheduling schemes in multi-user MIMO systems were compared and analyzed. The two schemes both adopted the lbit feedback-based scheduling algorithm. The difference of them is that the base station in scheme one randomly scheduled users only according to the imtantaneous CSI, while the base station in scheme two scheduled users using both the instantaneous CSI and the spatial correlation information. After the analysis of the two schemes from the aspect of algorithm process, the advantages and disadvantages of the two schemes were compared according to the utilization of spatial correlation, the number of users being served simultaneously and the system capacity respectively.
