The Watermark benchmark for underwater acoustic modulation schemes
(2017)
Watermark is a freely available benchmark for physical-layer schemes for underwater acoustic communications. It allows researchers to test and compare algorithms for the physical layer under realistic and reproducible ...
Measurements and modeling of effects of out-of-plane reverberation on the power delay profile for underwater acoustic channels
(2015)
Long reverberation tails are often observed in shallow-water acoustic channel impulse responses (CIRs). Examples from three significantly different environments along the Norwegian coast are presented. It is shown that 2-D ...
Validation of replay-based underwater acoustic communication channel simulation
(2013)
This paper discusses validation methods for underwater acoustic communication channel simulators, and validates direct and stochastic replay of underwater acoustic communication channels as implemented in a channel simulator ...
Under-ice mid-frequency acoustic transmissionand communication in two Arctic Oceanenvironments
(2023-02-23)
This paper presents data from mid-frequency (4−8 kHz) under-ice acoustic transmission and communication experiments in the Nansen Basin and in the Beaufort Sea of the Arctic Ocean. Measured impulse responses to range ~10 ...
Exact 3D scattering solutions for spherical symmetric scatterers
(2018)
In this paper, exact solutions to the problem of acoustic scattering by elastic spherical symmetric scatterers are developed. The scatterer may consist of an arbitrary number of fluid and solid layers, and scattering with ...
Generalization and stabilization of exact scattering solutions for spherical symmetric scatterers
(2022-08-29)
In a previous work the authors described a fast high-fidelity computer model for acoustic scattering from multi-layered elastic spheres. This work is now extended with a scaling strategy significantly mitigating the problem ...
Isogeometric Analysis of Acoustic Scattering using Infinite Elements
(2018)
Isogeometric analysis (IGA) has proven to be an improvement on the classical finite element method (FEM) in several fields, including structural mechanics and fluid dynamics. In this paper, the performance of IGA coupled ...
