Abstract
Free space optics (FSO) is one of the sprouting technologies in optical communication systems domain.It can be employed as an alternative for the conventional radio frequency (RF) links to work out thecurrent limitations in communication systems. But, the major drawback in FSO communication is theeffect of random environment conditions on its performance. In this paper, we analyze the bit errorrate (BER) and outage performance of single-input single-output (SISO) and multiple-input multiple-output (MIMO) FSO systems in strong atmospheric turbulence using binary phase shift keying subcarrierintensity modulation (BPSK-SIM) signaling technique. The closed-form expressions are derived and theresults are realized in terms of 2D and 3D plots.
