Toward continuous underwater acoustic communications
OCEANS 2008, 2008The paper addresses the technical challenges and approaches for semi-continuous underwater acoustic communications, i.e., transmission of long packets under different environmental conditions without periodic training. The packet length is normally constrained by the channel coherence time for a given bandwidth, beyond which channel tracking using an ...

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 ...

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
