Dynamic Optical Wireless Communication Channel Characterization Through Air-Water Interface

Abstract

In this paper, we consider an optical wireless communication system model whose channel consists of three parts: underwater channel, atmosphere channel and the interface between air and water. To better approximate the reality, besides the effect of random air-water interface, we consider the impact of ocean current which leads to misalignment between the transmitter and receiver. On the basis of this model, we explore the communication viability and simulate its link gain and time delay. Monte Carlo simulation results show that the dynamic air-water interface extends the communication opportunities, especially when there is no direct path between the underwater nodes and airborne base station.
