| contents | Compared with line-of-sight (LOS) communication, nonline-of-sight (NLOS) underwater wireless optical communication (UWOC) systems have garnered extensive attention because of their heightened suitability for the intricate and dynamic underwater environment. In the NLOS channel, photons can reach the receiver by sea surface reflection or particle scattering. However, research lacks comprehensive channel models that incorporate sea surface reflection and particle scattering. Moreover, the presence of ocean turbulence introduces random fluctuations in the received optical signal based on the average light intensity. Consequently, this paper adopts the Monte Carlo simulation method (MCS) to solve the fading-free impulse response of the joint reflection-scattering channel. Furthermore, a weighted double gamma function (WDGF) is proposed to characterize the channel impulse response (CIR). Based on the closed CIR model, the average bit error rate and the performance of the interruption probability of the UWOC system under turbulence are analyzed. The conclusions obtained are intended to assist in the design and performance evaluation of NLOS UWOC systems. |
