摘    要:作为一种多天线传输技术,空间调制(SM)近年来发展迅速,与传统的MIMO技术相比,能有效地避免信道间干扰(ICI)和多天线发射的同步问题。分析了空间调制技术的基本原理,并对天线接收算法进行了分类比较。通过仿真比较了SM与垂直贝尔实验室分层空时结构(V-BLAST),证明了SM性能上的优势,同时分析了SM对独立信道条件的依赖性。最后,空间调制研究热点以及一些亟待解决的问题得到了深入的讨论。

关 键 词:空间调制  信道间干扰  空移键控

Abstract:Spatial modulation (SM) is a rapidly developing transmission technique with multiple antennas in recent years. Compared with the traditional MIMO technology, SM can avoid interchannel interference (ICI) and multiple antennas synchronization effectively. This paper analyses the basic theory of SM and classifis the receiving algorithms of multiple antennas. Compared with the vertical Bell lab layered spacetime structure(V-BLAST) , SM has more superior performance. In addition, the dependence of SM on in correlied channel condition through simulation is also analyzed. At last, the hot spot of SM research and some problems needed to be addressed will be further discussed.
Keywords:spatial modulation(SM)  ICI  space shift keying
