The Impact of Demand Forecasting on Delay and Jitter in DVB-Based Beam-Hopping LEO Networks
Yekta Demirci, Guillaume Mantelet, Stéphane Martel +2
In LEO satellite networks utilizing beam hopping (BH), resource allocation plans must be committed well in advance. This inherent operational delay necessitates predicting future u…
Space-Based GNSS Radio Frequency Interference Detection Evaluation Through Multi-Satellite Data Integration
Anouar Boumeftah, Peter Klimas, Gunes Karabulut Kurt
Space-based GNSS reflectometry (GNSS-R) can detect terrestrial radio frequency interference (RFI) through elevated noise power in delay-Doppler map forbidden zones. This study eval…
Experimental Demonstration of a Real Time Wideband OFDM Generation in Sub-THz
Eray Güven, Nesrine Benchoubane, GüneŠKarabulut Kurt
Sub-terahertz (Sub-THz) wireless communications and their potential applications continue to attract significant attention and foster debate on the usage of their unused frequency…
A Novel Piecewise Atmospheric Attenuation Model for Free Space Optical Links in Vertical Heterogeneous Networks
Eylem Erdogan, Mohammed Elamassie, Ibrahim Altunbas +3
Free-space optical (FSO) communication is emerging as a key backhaul technology for next-generation vertical heterogeneous networks (VHetNets), whose architecture spans satellites,…
Leveraging Orbital Dynamics with RF Signal Features for Satellite Multi-Orbit Proximity Threat Detection
Anouar Boumeftah, Gunes Karabulut Kurt
Proximity-based interference is a growing threat to satellite communications, driven by dense multi-orbit constellations and increasingly agile adversarial maneuvers. We propose a…
Multi-Orbiter Continuous Lunar Beaming
Baris Donmez, Yanni Jiwan-Mercier, Sebastien Loranger +1
In this work, free-space optics-based continuous wireless power transmission between multiple low lunar orbit satellites and a solar panel on the lunar rover located at the lunar s…
