On Performance of Multiuser Underwater Wireless Optical Communication Systems
2020 International Conference on Computing, Networking and Communications (ICNC), 2020Non-orthogonal multiple access (NOMA) is an emerging multiple access technique and enjoys the benefits by enabling multiple users to multiplex in power domain. More recently, NOMA has been discussed in visible light communications (VLC) but less in underwater wireless optical communications (UWOC).

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.
