TL;DR: A promising underwater localization and positioning scheme based on this cellular network is presented and is used as infrastructure of centralized, decentralized and relay-assisted underwater sensor networks for high-speed real-time monitoring.

TL;DR: In this paper, a cellular underwater wireless optical code division multiple access (UW-OCDMA) network is proposed to provide broadband links for commercial and military applications, where the optical orthogonal codes are employed as signature codes of underwater mobile users.

TL;DR: In this article, the authors describe the use of multiplexing and the simultaneous transmission of multiple OAM beams for enhancing the capacity of communication systems and highlight the key advances and technical challenges in the areas of free-space and fiber communication links, mitigation of modal coupling and channel crosstalk effects, classical and quantum systems, and optical and radio frequency beam multiplexings.

TL;DR: In this article, a pilot-assisted self-coherent detection approach is proposed to overcome the effect of atmospheric turbulence in free-space optical communications, where the data is recovered by mixing a Gaussian local oscillator with a received Gaussian data beam.

TL;DR: A positioning system for underwater users is proposed based on the underwater wireless optical CDMA network and two different localization schemes namely Received Signal Strength (RSS) and Time of Arrival (TOA) are discussed and their performances in the presence of optical turbulence are explored.
