摘　　要：根据微波网络理论分析的基础,研究了基于微波网络理论的多天线阵列接收端的功率、信号相关、信道容量等性能。通过结合S参数法和网络分析理论对MIMO接收机的性能进行详细的研究。通过计算机对三种不同的匹配条件进行了仿真;包括特性阻抗匹配、自阻抗匹配和多端口共轭匹配(MC)。数值仿真结果表明,不同的匹配条件对系统性能的影响是有区别的,也即匹配网络对改善MIMO系统性能会起到重要作用。Based on the theoretical analysis of microwave network, the performance of power, signal correlation and channel capacity of multi antenna array receiver based on microwave network theory are studied. By combining the S parameter method and network analysis theory, the performance of MIMO receiver is studied in detail. Three different matching conditions are simulated by the computer, it conclucles the characteristic impedance matching, the self impedance matching and the multi port conjugate matching （MC）. Numerical simulation results show that the influence of different matching conditions on the performance of the system is different, that is, the matching network plays an important role in improving the performance of MIMO system.
