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…
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…
CASH: Context-Aware Smart Handover for Reliable UAV Connectivity on Aerial Corridors
Abdul Saboor, Zhuangzhuang Cui, Achiel Colpaert +2
Urban Air Mobility (UAM) envisions aerial corridors for Unmanned Aerial Vehicles (UAVs) to reduce ground traffic congestion by supporting 3D mobility, such as air taxis. A key chal…
Spatially Consistent Air-to-Ground Channel Modeling with Probabilistic LOS/NLOS Segmentation
Evgenii Vinogradov, Abdul Saboor, Zhuangzhuang Cui +1
