Underwater Wireless Optical Communication Systems: A Survey
2020 7th International Conference on Smart Structures and Systems (ICSSS), 2020Underwater wireless communication (UWC) means the transmission of data using wireless channels through the underwater, i.e. radio frequency waves (RF), acoustic waves and optical waves in an unguided water environment. In this review article we focus on underwater optical wireless communications (UWOCs) using optical waves as transmission medium. UWOCs

Beamforming Based Underwater Wireless Optical Communication Systems
2019 International Conference on Communication and Electronics Systems (ICCES), 2019The beamforming based underwater wireless optical communication (UWOC) systems with phase shift keying (PSK) modulation is elucidated in this work. UWOC is a powerful technology which is used for large speed underwater communications. Turbulence is the main mortifying factor of underwater, when light waves are propagating through underwater.
