Monte-Carlo-based optical wireless underwater channel modeling with oceanic turbulence

Abstract

Underwater optical wireless communication has attracted widespread attention due to its high bandwidth. The complex compositions of seawater affect the transmission of underwater optical signals. However, for underwater optical wireless channel modeling, the turbulence effect cannot be integrated into the Monte Carlo simulation framework for absorption and scattering. Based on the generalized Snell’s Law, we extend the multiple phase screen model to unify turbulence effects, absorption and scattering effects into the Monte Carlo simulation framework, which allows us to study the integration of absorption, scattering and turbulence effects on underwater channels simultaneously. The received intensity probability density distribution, spatial light intensity distribution and power loss are investigated. To the best of our knowledge, this is the first time to explore the integration of absorption, scattering and turbulence effects on underwater optical wireless channel.
