Abstract
The Underwater wireless optical communication (UWOC) may be a communication system that transmits data in an underwater environment using light. UWOC provides variety of advantages over the underwater radio frequency and acoustic techniques, including a broad unlicensed spectrum with high information bandwidth and low power requirements. A major purpose of this study is intended to grasp the simplest system architecture, practicality, and constancy of high-speed underwater optical communications thanks to various phenomena of propagation that affect the system's performance, like characterization of the channel, modulation techniques, and various noise sources caused by reflection, diffusing, and absorption. The Orthogonal Frequency Division Multiplexing (OFDM) accompanying Quadrature Amplitude Modulation (QAM) by employing Multi-Input-Multi-Output (MIMO) aims to boost data rate and range, which will benefit in the subsequent development of underwater optical communication. The system's performance was assessed in a high turbulent underwater channel and analyzed by changing the link range and the results are presented as comparisons between various data rates.
