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。

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 space-time 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.
