Free Space Optics is the technology that uses line-of-sight path for the communication between two points. The FSO uses beam of light to provide optical connection that can send and receive video, voice, and data information. The performance of modulation techniques such as Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK) are studied in the AWGN channel and the Rayleigh Channel. There are certain impairments associated with the FSO system. The effect of scintillation index and Free Space Path Loss (FSPL) are also considered in this work
