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…
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…
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…
Exploring O-RAN Compression Techniques in Decentralized Distributed MIMO Systems: Reducing Fronthaul Load
Mostafa Rahmani, Junbo Zhao, Vida Ranjbar +4
This paper explores the application of uplink fronthaul compression techniques within Open RAN (O-RAN) to mitigate fronthaul load in decentralized distributed MIMO (DD-MIMO) system…
Aliased Time-Modulated Array OFDM Transmit System
Marcin Wachowiak, André Bourdoux, Kamil Yavuz Kapusuz +1
The time-modulated array is a simple array architecture in which each antenna is connected to an RF switch that serves as a modulator. The phase shift is achieved by digitally cont…
