On Performance of Underwater Wireless Optical Communications Under Turbulence
2020 IEEE 17th Annual Consumer Communications & Networking Conference (CCNC), 2020In this paper, we consider the impact of turbulence on performance of UWOC systems and investigate capacity and bit-error rate (BER) of underwater wireless optical links under weak and strong turbulence by deriving the expressions of average capacity and BER.

On the Capacity of Underwater Optical Wireless Communication Systems
2021 Fifth Underwater Communications and Networking Conference (UComms), 2021In this paper, we first analyze the factors that affect the capacity of underwater optical wireless communication (UOWC) systems through deriving a new tight capacity upperbound. We find that the system capacity depends on the light wavelength in a complicated manner.

Analysis of underwater wireless optical communication system performance
Applied Optics, 2019Because the underwater channel environment is complicated, it is difficult to do an actual experiment in the ocean to analyze the performance of underwater wireless optical communication (UWOC) systems. In this study, the spot-expansion characteristics and time-domain broadening characteristics of underwater wireless optical signals are simulated and ...

A Complete Model for Underwater Optical Wireless Communications System
2018 11th International Symposium on Communication Systems, Networks & Digital Signal Processing (CSNDSP), 2018In this paper, we propose a system model by considering turbulence, scattering and absorption effects and noises including shot noise, thermal noise and background noise, for underwater optical wireless communications. The results are shown for the three different types of water by considering the different effects in the model.

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

Underwater wireless optical communication; recent advances and remaining challenges
2014 16th International Conference on Transparent Optical Networks (ICTON), 2014Because 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.
