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…
LITE: Lightweight Channel Gain Estimation with Reduced X-Haul CSI Signaling in O-RAN
David Goez, Marco Piazzola, Giulia Costa +6
Cell-Free Massive Multiple-Input Multiple-Output (CF-MaMIMO) in Open Radio Access Network (O-RAN) promises high spectral efficiency but is limited by frequent Channel State Informa…
Dualband OFDM Delay Estimation for Multi-Target Localization
Jialun Kou, Achiel Colpaert, Zhuangzhuang Cui +1
Integrated localization and communication systems aim to reuse communication waveforms for simultaneous data transmission and localization, but delay resolution is fundamentally li…
Experimental Validation of SBFD ISAC in an FR3 Distributed SIMO Testbed
Bixing Yan, Kwadwo Mensah Obeng Afrane, Achiel Colpaert +3
Integrated sensing and communication (ISAC) is a key enabler for future radio networks. This paper presents a sub-band full-duplex (SBFD) ISAC system that assigns non-overlapping O…
Inter-patient ECG Arrhythmia Classification with LGNs and LUTNs
Wout Mommen, Lars Keuninckx, Paul Detterer +2
Deep Differentiable Logic Gate Networks (LGNs) and Lookup Table Networks (LUTNs) are demonstrated to be suitable for the automatic classification of electrocardiograms (ECGs) using…
Trajectory-Aware Air-to-Ground Channel Characterization for Low-Altitude UAVs Using MaMIMO Measurements
Abdul Saboor, Zhuangzhuang Cui, Achiel Colpaert +3
This paper presents a comprehensive measurement-based trajectory-aware characterization of low-altitude Air-to-Ground (A2G) channels in a suburban environment. A 64-element Massive…
