Abstract:
Optical intelligent reflecting surfaces (OIRS) offer a promising solution for enhancing non-line-of-sight (NLOS) underwater wireless optical communication (UWOC) by adaptively controlling optical wave propagation. This work analyzes PMS- and OIRS-assisted NLOS UWOC systems and compares them with a benchmark scheme based on total internal reflection (TIR). Closed-form expressions for the PDF, CDF, average spectral efficiency (SE), energy efficiency (EE), outage probability, and bit error rate (BER) are derived using the Mellin inverse transform, Meijer’s G-function, and Fox’s H-function, along with an asymptotic SE analysis at high SNR. A machine learning–based OIRS configuration framework is further introduced, employing deep reinforcement learning for dynamic surface optimization and neural network–based channel prediction to adapt to underwater turbulence.
MATLAB Simulation results shows that the proposed learning-enabled OIRS-assisted UWOC system significantly outperforms PMS-assisted and TIR-based schemes, achieving higher SE and EE with reduced outage probability and BER.
