Experimental study of MIMO wireless optical communication diversity reception system

文中在分析了MIMO无限光通信系统的组织结构和系统构成基础上,对其中的原理和参数进行简要的描述,并且选出最符合分集接收系统实验的器件和结构,搭建了关于MIMO无线光通信的实验平台,而且在此基础上进行实验测试和优化处理,得出了结论,即阵列光天线可以改善无线光通信系统中的通信效果与质量,且可以增大信号的信噪比。通过实验与理论相结合的方式得出结论:光纤光栅作为滤波器可以有效的改善大气通信系统的性能。

This article based on the analysis of the optical communication system MIMO unlimited organizational structure and system configuration, based on the principles and parameters for which a brief description, and select the device and the struc- ture of the most consistent with diversity reception system experiments, built on MIMO wireless optical communications the ex- perimental platform, and on the basis of experimental testing and optimization, came to the conclusion that the light array an- tenna can improve wireless optical communication system communication effectiveness and quality, and can increase the signal to noise ratio. On this basis, the fiber grating obtained by a combination of experimental and theoretical approach as a filter can effectively improve the performance of air communication systems.
