Energy-Saving Cell-Free Massive MIMO Precoders with a Per-AP Wideband Kronecker Channel Model

no code implementations27 Sep 2023 Emanuele Peschiera, Xavier Mestre, François Rottenberg

We study cell-free massive multiple-input multiple-output precoders that minimize the power consumed by the power amplifiers subject to per-user per-subcarrier rate constraints.

Deep Unfolding for Fast Linear Massive MIMO Precoders under a PA Consumption Model

no code implementations25 Apr 2023 Thomas Feys, Xavier Mestre, Emanuele Peschiera, François Rottenberg

Massive multiple-input multiple-output (MIMO) precoders are typically designed by minimizing the transmit power subject to a quality-of-service (QoS) constraint.

Self-Supervised Learning of Linear Precoders under Non-Linear PA Distortion for Energy-Efficient Massive MIMO Systems

no code implementations13 Oct 2022 Thomas Feys, Xavier Mestre, François Rottenberg

Massive multiple input multiple output (MIMO) systems are typically designed under the assumption of linear power amplifiers (PAs).

Floor Map Reconstruction Through Radio Sensing and Learning By a Large Intelligent Surface

no code implementations21 Jun 2022 Cristian J. Vaca-Rubio, Roberto Pereira, Xavier Mestre, David Gregoratti, Zheng-Hua Tan, Elisabeth de Carvalho, Petar Popovski

Environmental scene reconstruction is of great interest for autonomous robotic applications, since an accurate representation of the environment is necessary to ensure safe interaction with robots.

User Clustering for Rate Splitting using Machine Learning

no code implementations23 May 2022 Roberto Pereira, Anay Ajit Deshpande, Cristian J. Vaca-Rubio, Xavier Mestre, Andrea Zanella, David Gregoratti, Elisabeth de Carvalho, Petar Popovski

Hierarchical Rate Splitting (HRS) schemes proposed in recent years have shown to provide significant improvements in exploiting spatial diversity in wireless networks and provide high throughput for all users while minimising interference among them.

Exclusive Group Lasso for Structured Variable Selection

1 code implementation23 Aug 2021 David Gregoratti, Xavier Mestre, Carlos Buelga

It is also shown that such an algorithm can be tailored to match more rigid structures than plain exclusive group sparsity.
