Dataset for Channel State Information (CSI) Delay-Doppler Analysis for Joint Communication and Sensing

This dataset has been used to conduct an analysis of the CSI in the delay-Doppler domain to gain insight into the potential and limitations of CSI-based ambient sensing. The dataset contains many CSI traces collected in an indoor environment in the presence of people performing different activities. All the data were collected with commercial Wi-Fi systems using IEEE 802.11ax and 20/40/80-MHz-wide channels. If you use this dataset, please cite our work as one of the associated publications. The publications associated to the various versions of this dataset are: "Delay-Doppler Domain Feature Extraction for Explainable Wi-Fi Activity Recognition via SVM", E. Tonini, R. Lo Cigno, and E.
