Performance Analysis of DF Relaying Assisted Underwater Visible Light Communication System

Underwater optical wireless communication plays an important role in the oceanography research, offshore exploration, climate monitoring, tactical surveillance and has attracted interest of military, industry, scientific and research community. In this paper, mixed satellite-underwater visible light communication (UWVLC) decode and forward (DF) cooperative system is proposed to help establish the connectivity between underwater scenario with the terrestrial regions via satellite for both oceanic monitoring as well as communication. The link between satellite and floating vessel (FV) is modeled by Shadowed-Rician fading channel and the UWVLC link is characterized by the mixture Exponential-Generalized Gamma (EGG) distribution. In particular, for the dual-hop satellite-UWVLC system, we derive the exact closed-form expressions for the average bit error rate (BER) in terms of a generalized Fox-H function. Furthermore, performance of the system is analyzed for various parameters such as air bubble levels, temperature gradient and saline level of water to validate the feasibility of the proposed system model.
