摘要
文章讨论了在时变无线信道下多天线无线通信系统中MIMO机制的选择问题,并提出一种基于调制编码(Modulation and Coding Scheme,MCS)信息的MIMO机制选择方案。该方案通过对MCS信息进行统计和分析,自适应的选择MIMO机制以获得最大吞吐量。与已有MIMO选择方案相比,该算法不仅仍能准确地选择出合适的MIMO机制,而且易于实现,更容易应用于实际系统中。
How to select the appropriate MIMO scheme in the multi-antenna wireless communication system with time-varying MIMO channel is discussed, and a MCS information based adaptive MIMO scheme selection algorithm is proposed in this paper. This proposed algorithm can find the right MIMO scheme to achieve the maximum throughput by the analysis; and statistics of MCS information. As compared with existing MIMO selection schemes, it can choose the appropriate MIMO scheme with less complexity but higher feasibility.
