Abstract
Free-space optics (FSO) has become one of the prominent solutions to the bandwidth limitation of radio frequency links. But, the FSO system performance is purely dependent on atmospheric conditions. Atmospheric turbulence, scintillation, and pointing errors are the major deteriorations in FSO communications. Multiple input multiple output (MIMO) or spatial diversity structure can improve the performance of the FSO system. The bit error rate (BER) performance of the MIMO FSO system employing binary polarization shift keying using optimal combining is analyzed. We have derived a closed form expression for the BER of the system, and the results are compared against the single input single output system.
