Channel modeling for underwater optical communication [PDF]
2011 IEEE GLOBECOM Workshops (GC Wkshps), 2011 We consider in this paper channel modeling for underwater optical channels. In particular, we focus on the channel impulse response and quantify the channel time dispersion under different conditions of water type, link distance, and transmitter/receiver parameters.

Laser based underwater communication systems [PDF]
2016 18th International Conference on Transparent Optical Networks (ICTON), 2016 We report on recent progress in the field of visible light communications including direct modulation of blue laser devices at data rates beyond 10 Gbit/s, and the transmission of 2.5 Gbit/s OOK data through water. We also discuss the advantages of operating with single mode laser devices and matched filtering at the receiver in the context of ...

AUV-Based Side-Scan Sonar Real-Time Method for Underwater-Target Detection
Journal of Marine Science and Engineering, 2023 The limitations of underwater acoustic communications mean that the side-scan sonar data of an autonomous underwater vehicle (AUV) cannot be transmitted back and processed in real time, which means that targets cannot be detected in real time. To address
