Presentation at SDR Academy 2025

This presentation, given at the SDR Academy during the HAM radio conference 2025 in Friedrichshafen, covers some additional technical details of ESPARGOS.

Paper on Passive Channel Charting

In this paper, we propose passive channel charting, a novel passive target localization technique that is, like conventional channel charting, based on dimensionality reduction.

Passive Target Localization

Localization of passive targets (human or robot) based on clasical triangulation or based on two different neural network approaches (supervised or self-supervised "passive channel charting").

Channel Charting with ESPARGOS

Indoor localization with Siamese Neural Network-based and Triplet Neural Network-Based Channel Charting. Also contains code for triangulation-based localization.

Paper on ESPARGOS Datasets

This research paper describes what goes into producing one of our ESPARGOS datasets. It also briefly explains how to apply Channel Charting to one of the datasets.

Paper on ESPARGOS Hardware Architecture

This research paper explains how the hardware architecture of ESPARGOS achieves phase-coherence. Despite describing an older hardware revision, the basic explanations and results still apply.
