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
