Free Space Optical (FSO) communication has gained significant importance in several applications and wireless communication. Atmospheric conditions largely affect the performance of FSO system making the transmitted signal susceptible to the degrading effects of atmospheric turbulence and pointing errors. In this paper, an analysis OOK modulated signal is presented under different atmospheric conditions, with and without pointing error and then a brief comparison of the simulated results is done.
