摘　　要：空间相关性是实际的多入多出无线通信系统必须要解决的损伤之一。多入多出系统的信能受空间相关性的影响非常大,有必要对天线的空间相关性进行深入研究。利用数学分析,介绍了两种用于多入多出系统的空间相关性的精确分析与近似分析的模型。并利用Matlab对模型进行仿真。仿真结果表明,近似分析在一定的条件下可替代精确分析。Spatial correlation is one of the impairments practical MIMO wireless communication systems have to cope with. The performance of MIMO system is mostly affected by the channel correlation, it needs to study the channel correlation. Using mathematical analysis, two kinds of exact and approximate equations on spatial correlation are introdueed. Numerical simulations are performed with Mat lab to verify the proposed formula. The results show that approximate analysis can replace the exact analysis in some cases.
