Comparative Analysis and Behavioral Modelling of Power Amplifiers in FR3
Cel Thys, Rodney Martinez Alonso, Ali H Alsarraf +3
Power amplifier (PA) nonlinearity is a critical transmitter impairment in the upper mid-band (7 GHz to 24 GHz), designated as Frequency Range 3 (FR3) in emerging 6G standardisation…
Low Complexity Neural Network Digital Predistortion of Wideband Power Amplifiers through Feature Selection
Cel Thys, Rodney Martinez Alonso, Ali H Alsarraf +2
Due to the continuous increase in communication bandwidth and the use of highly efficient yet nonlinear power amplifiers, Digital Predistortion (DPD) algorithms are becoming increa…
Efficient Channel Autoencoders for Wideband Communications leveraging Walsh-Hadamard interleaving
Cel Thys, Rodney Martinez Alonso, Sofie Pollin
This paper investigates how end-to-end (E2E) channel autoencoders (AEs) can achieve energy-efficient wideband communications by leveraging Walsh-Hadamard (WH) interleaved converter…
Inter-Cell Interference Rejection Based on Ultrawideband Walsh-Domain Wireless Autoencoding
Rodney Martinez Alonso, Cel Thys, Cedric Dehos +2
This paper proposes a novel technique for rejecting partial-in-band inter-cell interference (ICI) in ultrawideband communication systems. We present the design of an end-to-end wir…
Near-Field Spatial non-Stationary Channel Estimation: Visibility-Region-HMM-Aided Polar-Domain Simultaneous OMP
Thibaut Ceulemans, Cel Thys, Robbert Beerten +2
This work focuses on channel estimation in extremely large aperture array (ELAA) systems, where near-field propagation and spatial non-stationarity introduce complexities that hind…
Building a real-time physical layer labeled data logging facility for 6G research
Franco Minucci, Raquel Marina Noguera Oishi, Haoqiu Xiong +7
This work describes the architecture and vision of designing and implementing a new test infrastructure for 6G physical layer research at KU Leuven. The Testbed is designed for phy…
Walsh-domain Neural Network for Power Amplifier Behavioral Modelling and Digital Predistortion
Cel Thys, Rodney Martinez Alonso, Antoine Lhomel +4
This paper investigates the use of Neural Network (NN) nonlinear modelling for Power Amplifier (PA) linearization in the Walsh-Hadamard transceiver architecture. This novel archite…
