This repository provides FIR channel models which mimic ultrasound in-body communication scenarios. More specifically, we performed ultrasound channel characterization of regularly-shaped gelatin phantoms with scattering materials, using a custom ultrasound test bed.
If you use this data, please cite "T.Bos et al. "Enabling Ultrasound In-Body Communication: FIR Channel Models and QAM Experiments", IEEE Transactions on Biomedical Circuits and Systems, 2018 (Early Access) (DOI 10.1109/TBCAS.2018.2880878)". Take a look at our paper currently available at ieee xplore.
The data is stored in .mat files, which can be loaded both in matlab or python/scipi. The helper scripts and example scripts are written in matlab scripting language.
A full description of the different FIR channel models can be found on this page, together with photographs taken during the measurement campaign.
Example scripts on how to visualize the FIR channels, or how to use them in your communication modem, are provided in the examples/ folder.
