Single scattering impulse response modeling of underwater wireless optical channels

Abstract

In underwater wireless optical communications (UWOC), impulse response is essential for performance evaluation and system design. However, most prior works on impulse response modeling for UWOC links utilize curve fitting of Monte Carlo simulation results and require remodeling once the link geometry or system configuration is changed. In this paper, we derive an analytical formula to model the single scattering component of impulse response. Simulation results have shown that the analytical model agrees with the Monte Carlo simulations for various link ranges, receiver apertures, launch angles and water types. The proposed model is beneficial for evaluation of UWOC links and further study on the impulse response with full components.Index Terms-Underwater wireless optical communications, impulse response, single scattering.

New Monte Carlo Integration Models for Underwater Wireless Optical Communication

“…Recent works explore the possibility to express the propagation of photons as a probabilistic mechanism [71]- [75]. In [72], [73] the single scattering effect was investigated first, before to generalize to multiple scattering and to apply Monte Carlo Integration techniques. In [71], [74], [75], multiple scattering are considered, in 2D in [74] or in 3D for others.…”
