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…
Profit-Driven Pricing and SLA-Aware Reserve Sizing for Multi-Tenant Satellite O-RAN Services
Manobendu Sarker, Gunes Karabulut Kurt, Wael Jaafar
This paper studies a multi-tenant resource allocation problem in a satellite open radio access network (O-RAN) wholesale setting, where heterogeneous traffic classes share a time-v…
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,…
Energy Efficient Traffic Scheduling For Optical LEO Satellite Downlinks
Ethan Fettes, Pablo G. Madoery, Halim Yanikomeroglu +3
In recent years, the number of satellites in orbit has increased rapidly, with megaconstellations like Starlink providing near-global, delay-sensitive communication services. Howev…
