| Abstract: | FSO system has the advantages of high bandwidth,high speed,high stability,immunity to external EMI source and better security property.Terrestrial FSO system is badly influenced by the atmospheric signal channel,so it is of great importance to research and conclude the property of the atmospheric channel.In this paper,the atmospheric composition and its attenuation property of the FSO system was discussed,after which the theoretical equations of the attenuation were given.Due to the pain in unavailability o... |
