ECO-Friendly Underwater Acoustic Communications
Proceedings of the International Conference on Underwater Networks & Systems, 2017This paper introduces the idea of ECO-friendly underwater acoustic communications via utilizing prediction techniques. The ultimate goal of the research is to avoid the interference caused by man-made noise to marine mammals. Specifically, we first analyze the necessity and the advantage of prediction in underwater environments.

OFDMA for underwater acoustic communications
2011 49th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2011We investigate the possibility of using orthogonal frequency division multiple access (OFDMA) for design of efficient underwater acoustic (UWA) networks. The major challenge for the OFDMA-based UWA communication systems is the Doppler-induced frequency scaling, which may cause severe intercarrier interference (ICI), and depending on the particular user

Optimizing Adaptive Communications in Underwater Acoustic Networks
OCEANS 2019 MTS/IEEE SEATTLE, 2019We consider an Underwater Acoustic Network (UAN) where each node is equipped with a suite of signals and so there is the flexibility to aim for different bit rates at each transmission slot. A Cross-Entropy (CE) centralized algorithm is explored to optimize the combination of modulation scheme and transmission power level in the presence of unreliable ...

Underwater acoustic communications using quasi-orthogonal chirps
2017 51st Asilomar Conference on Signals, Systems, and Computers, 2017We propose a quasi-orthogonal chirp waveform design technique for underwater acoustic communications and study the correlation performance of binary linear chirp waveforms under different bandwidth and time constraints. Specifically, we consider binary information symbols that are carried over optimized binary linear chirp waveforms and transmitted ...

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 ...
