Learning-Free Hierarchical Joint Estimation of AoA, Pointing Error, Receiver Jitter, and Turbulence in Multi-Aperture FSO Systems
Mahtab Dashtebozorgi, Meysam Ghanbari, Rula Ammuri +2
This paper proposes a learning free hierarchical estimator for jointly recovering the angle of arrival (AoA), transmitter pointing error, receiver induced jitter, and per aperture…
Progressively Attenuated Multi-Branch Reception for Inter-HAPS Optical Links
Meysam Ghanbari, Betul Beidas, Wasiu O. Popoola +3
Inter HAPS optical links can experience receiver saturation at short separations and become signal to noise ratio (SNR) limited at longer distances. This work proposes a saturation…
OHL-Assisted All-Optical Regenerative Relaying for Pointing-Impaired M-PAM Inter-Satellite Links
Meysam Ghanbari, Mohammad Taghi Dabiri, Zain Ali +4
Rapid inter-satellite traffic growth in LEO constellations demands spectrally efficient, low-latency optical relaying. While amplify and forward (AF) relays are latency-efficient,…
When Future Communications Shift Toward Narrow Beams: A Forward Looking Survey on Pointing Errors and Alignment Limits
Meysam Ghanbari, Mohammad Taghi Dabiri, Osamah S. Badarneh +4
Directional links in free-space optical (FSO), millimeter-wave (mmWave), and terahertz (THz) systems are a cornerstone of emerging 6G networks, yet their reliability is fundamental…
QoS- and Physics-Aware Routing in Optical LEO Satellite Networks via Deep Reinforcement Learning
Mohammad Taghi Dabiri, Rula Ammuri, Mazen Hasna +1
Optical inter-satellite links (ISLs) are becoming the principal communication backbone in modern large-scale LEO constellations, offering multi-Gb/s capacity and near speed-of-ligh…
Towards City-Scale Quantum Timing: Wireless Synchronization via Quantum Hubs
Mohammad Taghi Dabiri, Mazen Hasna, Rula Ammuri +2
This paper presents a novel wireless quantum synchronization framework tailored for city-scale deployment using entangled photon pairs and passive corner cube retroreflector (CCR)…
