A Survey of Underwater Optical Wireless Communications

IEEE Communications Surveys & Tutorials, 2017
Underwater wireless communications refer to data transmission in unguided water environment through wireless carriers, i.e., radio-frequency (RF) wave, acoustic wave, and optical wave. In comparison to RF and acoustic counterparts, underwater optical wireless communication (UOWC) can provide a much higher transmission bandwidth and much higher data ...

Link misalignment for underwater wireless optical communications

2015 Advances in Wireless and Optical Communications (RTUWO), 2015
Absorption and scattering processes respectively cause intensity attenuation and direction deviation of photons during their propagation through underwater environment and therefore affect the spatial and temporal distribution of light intensity.

Beamforming Based Underwater Wireless Optical Communication Systems

2019 International Conference on Communication and Electronics Systems (ICCES), 2019
The 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.

Underwater wireless optical communication; recent advances and remaining challenges

2014 16th International Conference on Transparent Optical Networks (ICTON), 2014
Because of its ability of providing very high data transmission rates over distances up to several tens of meters, underwater wireless optical communication (UWOC) has attracted considerable interest during the past few years. The underwater channel is a challenging environment, especially because of its high attenuation.
