Abstract
In this paper, we consider an amplify-and-forward (AF) optical relaying to enhance the performance of the underwater wireless optical communication (UWOC) system with a negligible line-of-sight (LOS) link over the oceanic turbulence with pointing errors. We analyze the relay-assisted system’s end-to-end performance, which consists of complicated probability distribution functions. We derive analytical expressions of the outage probability, average signal-to-noise ratio (SNR), and ergodic rate in terms of UWOC system parameters. We also develop an exact integral-form expression of these performance metrics using the half-harmonic mean of individual SNRs to validate the tightness of the derived analytical expressions. The numerical and simulation analysis shows that the proposed dual-hop relaying has significant performance improvement comparing the direct transmission over considered channel impairments. The considered system also provides a significant gain in the average SNR and ergodic rate for practical scenarios of UWOC deployment.
