Spatially Consistent Air-to-Ground Channel Modeling and Simulation via 3D Shadow Projections
Evgenii Vinogradov, Aymen Fakhreddine, Abdul Saboor +2
We present an approach for spatially-consistent semi-deterministic Air-to-Ground (A2G) channel modeling in Unmanned Aerial Vehicle-assisted networks. We use efficient 3D building s…
Frequency Diverse Array OFDM Transmit System with Partial Overlap in Frequency
Marcin Wachowiak, André Bourdoux, Sofie Pollin
A frequency-diverse array (FDA) is an alternative array architecture in which each antenna is preceded by a mixer instead of a phase shifter. The mixers introduce a frequency offse…
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…
Analytical Modeling of Batteryless IoT Sensors Powered by Ambient Energy Harvesting
Jimmy Fernandez Landivar, Andrea Zanella, Ihsane Gryech +2
This paper presents a comprehensive mathematical model to characterize the energy dynamics of batteryless IoT sensor nodes powered entirely by ambient energy harvesting. The model…
