Abstract
For studying the effects of atmospheric scattering to optical signals,taking rain particles as an example, starting from its physical properties and employing Mie scattering theory and Joss raindrop spectrum distribution, the light intensity attenuation coefficient caused by rain particles'scattering was calculated.On this basis,the scattering effect on the performance of the free space optical communication orthogonal frequency division multiplexing(FSO-OFDM) system was analyzed.The results show that the FSO-OFDM system performance in scattering channel primarily depends on the variance of light intensity caused by scattering,secondly depends on light intensity attenuation coefficient caused by scattering.
