Design and Analysis of MIMO FSO System and WDM FSO System for Leh (Ladakh), India under Worst Weather Conditions

Abstract

Free space optics (FSO) as an optical wireless communication gained great attention to manage the disaster problem by providing license-free highly secure transmission with low-cost deployment and high bandwidth. Besides all these, atmospheric turbulence-induced fading can become a major challenge for FSO systems as it affects their performance. This paper proposed a novel design for multiple-input multiple-output (MIMO) FSO and hybrid wavelength division multiplexing (WDM) with multiple beams FSO systems by considering the rain, fog, dry snow, scintillation loss, geometric loss, and Rytov variance over Gamma-Gamma distribution. The results are offered in the form of Bit Error Rate (BER), Quality Factor (QF), and Eye Diagrams.
