Coordination of Ground-to-Space Reference Networks for High-Precision GNSS
Xue Xian Zheng, Xing Liu, José A. López-Salcedo +2
High-precision Global Navigation Satellite System (GNSS) services rely on accurate orbit, clock, atmospheric, and hardware-bias corrections generated from reference observations. T…
Physically Consistent Channel Modeling and Signal Processing for Reconfigurable Wireless Systems
Ahmad Dkhan, Simon Tarboush, Hadi Sarieddeen +3
Reconfigurable antennas are increasingly integrated into multi-antenna communication systems to exploit large apertures while reducing the hardware complexity, energy consumption,…
Analysis of UAV-Enabled IoT Networks with Energy Harvesting and Wake-Up Radio
Anthony Khairallah, Nour Kouzayha, Tareq Y. Al-Naffouri +1
This paper investigates an unmanned aerial vehicle (UAV)-enabled Internet of Things (IoT) architecture that integrates wake-up radio (WuR) and energy harvesting for sustainable dev…
Decentralized GNSS at Global Scale via Graph-Aware Diffusion Adaptation
Xue Xian Zheng, Xing Liu, Tareq Y. Al-Naffouri
Network-based Global Navigation Satellite Systems (GNSS) underpin critical infrastructure and autonomous systems, yet typically rely on centralized processing hubs that limit scala…
Rare-Event Simulation of Outage Probability in GSC/MRC Systems under Rician Fading
Mahmoud Ghazal, Nadhir Ben Rached, Tareq Al-Naffouri
This paper studies the estimation of outage probability in GSC/MRC SIMO systems under Rician fading in the rare-event regime. The difficulty arises from the evaluation of the CDF o…
