Toward Energy-Efficient Massive MIMO: Graph Neural Network Precoding for Mitigating Non-Linear PA Distortion
Thomas Feys, Liesbet Van der Perre, François Rottenberg
Massive MIMO systems are typically designed assuming linear power amplifiers (PAs). However, PAs are most energy efficient close to saturation, where non-linear distortion arises.…

Information-Theoretic Study of Time-Domain Energy-Saving Techniques in Radio Access
François Rottenberg
Reduction of wireless network energy consumption is becoming increasingly important to reduce environmental footprint and operational costs. A key concept to achieve it is the use…
