Wireless Channel Charting: Theory, Practice, and Applications
Paul Ferrand, Maxime Guillaud, Christoph Studer +1
Channel charting is a recently proposed framework that applies dimensionality reduction to channel state information (CSI) in wireless systems with the goal of associating a pseudo…
DNN-based Localization from Channel Estimates: Feature Design and Experimental Results
Paul Ferrand, Alexis Decurninge, Maxime Guillaud
We consider the use of deep neural networks (DNNs) in the context of channel state information (CSI)-based localization for Massive MIMO cellular systems. We discuss the practical…
Triplet-Based Wireless Channel Charting: Architecture and Experiments
Paul Ferrand, Alexis Decurninge, Luis G. Ordoñez +1
Channel charting is a data-driven baseband processing technique consisting in applying self-supervised machine learning techniques to channel state information (CSI), with the obje…
High-Rate Regular APSK Constellations
Paul Ferrand, Marco Maso, Valerio Bioglio
The majority of modern communication systems adopts quadrature amplitude modulation (QAM) constellations as transmission schemes. Due to their square structure, however, QAM do not…
CSI-based Outdoor Localization for Massive MIMO: Experiments with a Learning Approach
Alexis Decurninge, Luis García Ordóñez, Paul Ferrand +4
We report on experimental results on the use of a learning-based approach to infer the location of a mobile user of a cellular network within a cell, for a 5G-type Massive multiple…
Efficient Computation and Covariance Analysis of Geometry-Based Stochastic Channel Models
Paul Ferrand
In this work, we study a family of wireless channel simulation models called geometry-based stochastic channel models (GBSCMs). Compared to more complex ray-tracing simulation mode…
