摘要： 分析了MIMO下行链路中的多用户调度和功率分配方法，讨论了各种功率分配方法的多用户调度性能，并通过仿真实验对性能进行了比较。实验结果表明，在低信噪比条件下，二维注水功率分配的性能最佳，而在高信噪比条件下，各种功率分配方法的性能差别很小。
关键词: 多用户调度, 多输入多输出, 功率分配
Abstract: In this paper，we analyze multiuser scheduling and power allocation algorithms for MIMO downlink，and compute the performance of multiuser scheduling based on these power allocation algorithms.Some experiments are implemented to compare the performance.Numerical results show that the 2-D Water-Filling（WF） power allocation algorithm has the highest rate under low SNR，while there is little difference among three power allocation algorithms under high SNR.
Key words: multiuser scheduling, Multiple-Input Multiple-Output（MIMO）, power allocation
