Research on Atmospheric Channel Characteristic Test in Wireless Optical Communication System

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.
