Unsourced Random Access With Tensor-Based and Coherent Modulations
Alberto Rech, Alexis Decurninge, Luis G. Ordóñez
Unsourced random access (URA) is a particular form of grant-free uncoordinated random access wherein the users' identities are not associated to specific waveforms at the physical…
How to Identify and Authenticate Users in Massive Unsourced Random Access
Radosław Kotaba, Anders E. Kalør, Petar Popovski +4
Identification and authentication are two basic functionalities of traditional random access protocols. In ALOHA-based random access, the packets usually include a field with a uni…
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…
Covariance-Aided CSI Acquisition with Non-Orthogonal Pilots in Massive MIMO: A Large-System Performance Analysis
Alexis Decurninge, Luis G. Ordóñez, Maxime Guillaud
Massive multiple-input multiple-output (MIMO) systems use antenna arrays with a large number of antenna elements to serve many different users simultaneously. The large number of a…
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…
