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…
Depthwise Separable CNN for D-MIMO Indoor Localization with Data Reduction
Georgios Mystriotis, Rodney Martinez Alonso, Achiel Colpaert +1
Indoor localization using Distributed Multiple-Input Multiple-Output (D-MIMO) and machine learning (ML) achieves sub-centimeter accuracy but faces midhaul capacity bottlenecks when…
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…
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…
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…
