Article
This article presents extensive field tests of a fast-mode operation of the JANUS acoustic communication standard where the signals occupy high-frequency bands of 38 kHz spanning from 96 to 134 kHz instead of the nominal frequency band of 4.1 kHz spanning from 9.44 to 13.6 kHz specified in the standard. The fixed 32-chip preamble and the 144-chip b...
Article
This article investigates a robust receiver scheme for a single carrier, multiple-input–multiple-output (MIMO) underwater acoustic (UWA) communications, which uses the sparse Bayesian learning algorithm for iterative channel estimation embedded in Turbo equalization (TEQ). We derive a block-wise sparse Bayesian learning framework modeling the spati...

This paper analyzes the effects of metal structures in near-field Magneto-Inductive (MI) communication systems, where the transmitter and/or receiver coils may be close to large metal structures that have high magnetic permeability and conductivity. EMCoStudio simulations show that the presence of metal structure help to increase the coupling magni...

A set of six MATLAB Simulink laboratory exercises was previously designed in 2011 for an undergraduate analog/digital communication course. This paper presents our experience of a pilot test on these exercises, followed by their modification and enhancement, and concluding with an application of the modified exercises in the spring and fall 2012 of...
