无线光通信大气信道特性测试方法研究

Research on Atmospheric Channel Characteristic Test in Wireless Optical Communication System

大气信道是影响无线光通信质量的主要方面,为了全面掌握目前出现的信道测试方案,采用归纳总结和对比分析的方法,并结合实际测试,对信道测试方法进行研究。从大气衰减效应、光强闪烁效应以及光束漂移效应三方面测试内容出发,研究了各自运用的测试方法,并给出了相应的示意图,同时对比分析各自的优缺点,为采取合适的大气信道测试方法提供理论依据。

Atmospheric channel can affect the quality of wireless optical communication.To understand the current channel test method,the summarizing and analyzing methods are used in this paper,the test method of channel is studied by combining actual test.Starting from atmospheric attenuation,scintillation and beam drifting,the test methods of themselves are studied.To provide evidence and take appropriate test scheme,the advantages and disadvantages are summarized for the current test method.
