Abstract: This paper investigates BER performance of free space optical (FSO) communication over gamma-gamma turbulence channel. Which is widely accepted model for moderate to strong atmospheric turbulence condition. By considering Atmospheric turbulence, Pointing error and Atmospheric attenuation a combined Statistical model for intensity fluctuation at the receiver is described for given weather and pointing error condition, a closed form expression is derived for BER performance of FSO communication System.
Keywords: Free-Space Optical Communication, BER, Pointing Error, Atmospheric Turbulance., Atmospheric Loss.
