FSO (Free-Space Optical Communications) is a typeof optical communication that is transmitted over an open space.The irradiance fluctuation in a clear atmosphere is caused byTemperature variations in the atmosphere are minor but erratic.As a result, the Signal-to-Noise Ratio (SNR) is reduced, andperformance is reduced. BPSK has the best performance whenscintillation is not considered. Thus, BPSK is investigated in thiswork under the impact of air turbulence and meteorologicalvariables. The comparison of BPSK modulation scheme is done bysimulating turbulence in Log Normal and Negative ExponentialChannel.
