摘　　要：针对多输入多输出/智能天线(MIMO/SA)多天线系统,分析了影响系统性能的各个因素,建立基于模糊层次分析法的结构模型,确定各指标的权重,然后利用模糊数学原理得到结合方案中各指标的隶属度,得出各方案性能的模糊综合评估。仿真结果验证了该评估方法的准确性与有效性,对MIMO/SA技术的结合与应用提供了很好的参考和决策支持。The communication performance of multiple-input multiple-cutput smart antenna（MIMO/SA） communication system is investigated with a fuzzy analytic hierarchy process method. The factors that influence multi-antenna systems are analyzed, and the hierarchical structure model is established. Subsequently, the weights of each index are calculated. The membership of each index is obtained according to the principle of fuzzy mathematics. Finally~ the fuzzy comprehensive evaluation of the combination system is derived. The validity and accuracy of the evaluation method is confirmed by the simulation. This method provides a good reference for the application of MIMO/SA technologies.
