Abstract:

Underwater applications such as pollution monitoring, oceanographic data collection, offshore exploration, disaster prevention, and tactical surveillance applications are gaining popularity. Underwater acoustic communication systems can support long-range links but can achieve only a few tens of kbit/s failing to support high data rates. In this thesis, underwater visible light communication (UVLC) systems is investigated as an alternative and/or complementary technology to current acoustic systems. Particularly, we investigate the performance limit of UVLC and the benefits of link adaptation. We model the Underwater Optical Turbulence (UOT) channels and investigate the effect of turbulence on the system’s performance. Furthermore, we consider different fading mitigation techniques and investigate the achievable diversity orders. We, finally, consider a practical implementation of Underwater Sensor Networks (USNs) that requires the design of multiple access systems for supporting several sensor nodes and investigate the use of orthogonal and Non-Orthogonal Multiple Access
