The Underwater wireless opticalcommunication (UWOC) may be a communication systemthat transmits data in an underwater environmentusing light. UWOC provides variety of advantages over theunderwater radio frequency and acoustic techniques,including a broad unlicensed spectrum with highinformation bandwidth and low power requirements. Amajor purpose of this study is intended to grasp thesimplest system architecture, practicality, and constancy ofhigh-speed underwater optical communications thanksto various phenomena of propagation that affect thesystem's performance, like characterization of the channel,modulation techniques, and various noise sources causedby reflection, diffusing, and absorption. The OrthogonalFrequency Division Multiplexing (OFDM) accompanyingQuadrature Amplitude Modulation (QAM) by employingMulti-Input-Multi-Output (MIMO) aims to boost datarate and range, which will benefit in the subsequentdevelopment of underwater optical communication. Thesystem's performance was assessed in a high turbulentunderwater channel and analyzed by changing the linkrange and the results are presented as comparisonsbetween various data rates.
