ABSTRACTThis research endeavors to investigate the end‐to‐end performance metrics of a submerged AUV within the Single‐Input‐Multi‐Output underwater visible‐light communication (UVLC) system operating in moderate‐to‐strong turbulence channel conditions while accounting for pointing errors. In this study, the closed‐form expressions of analytical work are derived by using the probability density function and cumulative density function with a specific focus on Gamma‐Gamma distribution channel. The analytical framework is used to gain insight into the performance of developed UVLC system within the mixed waters. To validate the accuracy of the analytical approach under the Monte Carlo simulation methodology is used to improve the quality of service. The designed system aims to improve the reliability, practical applicability, and efficiency of the UVLC system, which is the paramount importance in emerging communication technologies.
