Multipath correlations in underwater acoustic communication channels
The Journal of the Acoustical Society of America, 2013Uncorrelated scattering (US), which assumes that multipath arrivals undergo uncorrelated scattering and are thus uncorrelated, has been the standard model for digital communications including underwater acoustic communications. This paper examines the cross-correlation of multipath arrivals based on at-sea data with different temporal coherence time ...

Adaptive Modulation and Coding for Underwater Acoustic Communication
2019 Eleventh International Conference on Ubiquitous and Future Networks (ICUFN), 2019In UWAC (Underwater Acoustic Communications), underwater acoustic channels change rapidly due to various environment condition. AMC (Adaptive Modulation and Coding) technique is efficient method for improving the system efficiency by changing transmission parameters according to channel conditions in underwater acoustic channels.

Underwater acoustic communications: Practice, modeling, and commentary
2010 7th International Symposium on Wireless Communication Systems, 2010At present, the realities of acoustic communications and undersea networks differ substantially from the expectations arising from academic theory and investigation. The issue is not that the fundamentals of communications theory do not apply, but rather the fact that the difficulties of the acoustic channel do not necessarily fit the assumptions ...

Ocean Variability Effects On Underwater Acoustic Communications
2007Abstract : This proposed research seeks to identify, explain, and ultimately predict, the factors that significantly alter the operational effectiveness of underwater acoustic communications through experimental work and theoretical analysis. The long-term goal is to develop reliable, high rate transceivers customized for coherent underwater acoustic ...

Overview of Underwater Acoustic Communication
2018Since radio signals are strongly attenuated in saltwater and often scattered by suspended particles (similar for optical signals), acoustic wave becomes major communication medium used in underwater environments (Preisig, Proceedings of the ACM international WS, underwater networks (WUWNet), Los Angeles, USA 2006, [1]). However, some characteristics of
