Due to ability to provide very high-speed transmission of data, without the use of any physical channel, free space optics (FSO) is an emerging as a promising communication technology. In FSO, the atmosphere ants as the channel and its turbulent nature causes degradation in bit error rate performance. This paper presents the performance evaluation of FSO communication for through Rayleigh fading environment. The equations for Bit Error Rate and Outage Probability are derived for BPSK, QPSK and 16-QAM modulation techniques. Simulation results has been presented out to calculate the FSO communication system performances derived for BPSK, QPSK and 16-QAM modulation techniques.
