Analysis and Approximation of a Spatially Wideband Antenna Array Factor
Marcin Wachowiak, André Bourdoux, Sofie Pollin
This work investigates the spatially wideband (SWB) antenna array factor (AF) of uniform linear arrays. First, the SWB AF approximation is derived for narrowband (NB) signals and a…
Near-Field Velocity Estimation and Doppler-Aware Localization in OFDM Massive MIMO
Qing Zhang, Dario Tagliaferri, Robbert Beerten +3
In Orthogonal Frequency Division Multiplexing (OFDM)-based massive Multiple-Input Multiple-Output (MIMO) near-field (NF) sensing, target motion induces an antenna-dependent bistati…
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…
Multi-/Uni-Cast Non-Orthogonal Multiple Access-Based INAC
Yaoyu Zhang, Xin Sun, Tianwei Hou +4
With the rapid development of satellite communication and navigation, there is an urgent need to integrate both technologies to achieve reliable communication and precise navigatio…
Joint Mobile User Positioning and Passive Target Sensing using Optimized Sequential Beamforming
Aymen Hamrouni, Sofie Pollin, Hazem Sallouha
Integrated sensing and communication (ISAC) relies on monostatic sensing (MS) and bistatic positioning (BP) to enable comprehensive environmental awareness and user localization. H…
