无线信道作为移动通信传输媒介,所有信息包含其中.要想充分利用频谱资源并且使传输信息的质量和容量最大化,信道特性应被清楚了解.同时,研究移动通信4G技术在复杂的无线传播环境中性能,离不开MIMO信道模型,因此对MIMO信道模型的分析十分必要.简要介绍了MIMO信道模型分类,并着重研究了基于几何分布统计信道模型的基础模型—SCM信道模型.最后对多普勒、时延扩展以及角度扩展仿真分析,验证了SCM信道建模的正确性.

@@@@Wireless channel, as the transmission medium of mobile communication, contain all the information. For full utilization of spectrum resource and maximization of quality and capacity of the transmitted information, it is necessary to clearly understand the channel characteristics. Meanwhile, the MIMO channel model should be required in the research iof 4G mobile communication technology in the complex wireless environment. This paper briefs the classification of MIMO channel, focuses on fundamental model-SCM, which is based on geometrically-distributed statistical model. Finally, the simulation on Doppler, delay spread and angle spread indicates the feasibility of SCM model.
