This letter discusses pointing errors in underwater optical communication caused by environmental disturbances and uncertainties that cannot be well measured controlled previous alignment methods. The bore-sight jitter effects are identified the motion model of mobile platform. We propose to use sensor suite includes a pressure sensor, super short baseline (SSBL) acoustic system, Doppler veloci...

An optical communication link is proposed for high speed point-to-point data transmission. The incorporates both fiber and wireless technologies. Kramer-Kronig coherent detection used due to its component implementation simplicity. Spatial multiplexing, via a multi-core followed by link, wavelength division multiplexing allow the efficient exploitation of all available degrees freedom. signal-t...

Many applications that could benefit from the underwater optical wireless communication technique face challenges in using this technology due to substantial, varying attenuation affects signal transmission through waterbodies. This research demonstrated convolutional neural networks (CNNs) readily address these problems. A modified CNN model was proposed recover original data of a non-return z...

This paper proposes the trajectory tracking problem between an autonomous underwater vehicle (AUV) and a mobile surface ship, both equipped with optical communication transceivers. The challenging issue is to maintain stable connectivity two vehicles within range. We define directed line-of-sight (LoS) link systems. transmitter mounted on AUV, while ship receiver. However, this channel needs pr...
