Underwater visible light communication (UVLC) has become a promising wireless signaling approach towards the 5G and 5G beyond (5GB) wireless networks. The depth-dependent photophysical characteristics of water such as pressure, density, temperature, and salinity fluctuations lead to the changes in the refraction index and turbulence of water. The channel turbulence is a bottleneck for optical signaling in aqueous mediums, especially in oceans; it also causes malfunctions in transceivers because of signal bias or pointing error. The paper examines the performance of the reflecting node as part of underwater optical communication system operating in visible light. Based on the experimental data obtained in the Southern Indian Ocean, the outage outcomes and bit-error-rate (BER) performances are considered. The performance metrics for the proposed system model are obtained under weak-turbulence channel conditions within Pulse-Amplitude Modulation (PAM) scheme. Additionally, the authors analytically present the closed-form expression for outage probability and a tight asymptotic expression for BER performance at high signal-to-noise (SNR) ratio that offers helpful insights into the influence of the medium on channel parameters and the system as a whole. The simulation results demonstrate operational capacity of the underwater communication system model.
