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…
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…
Multi-tap Digital Canceller for Full-Duplex Applications
Paul Ferrand, Melissa Duarte
We identify phase noise as a bottleneck for the performance of digital self-interference cancellers that utilize a single auxiliary receiver---single-tap digital cancellers---and o…
Trends and Challenges in Wireless Channel Modeling for an Evolving Radio Access
Paul Ferrand, Mustapha Amara, Maxime Guillaud +1
With the advent of 5G, standardization and research are currently defining the next generation of the radio access. Considering the high constraints imposed by the future standards…
