Digital-Twin-Aided Dynamic Spectrum Sharing and Resource Management in Integrated Satellite-Terrestrial Networks
Hung Nguyen-Kha, Vu Nguyen Ha, Ti Nguyen +4
The paper proposes a digital‑twin‑enabled framework for dynamic spectrum sharing and resource management in integrated satellite‑terrestrial networks, formulating and solving long‑…
Semantic Communication for Multi-Satellite Massive MIMO Transmission: A Mixture of Cooperative Modes Framework
Yafei Wang, Yuchen Zhang, Yiming Zhu +5
This paper investigates semantic communications (SemComs) for multi-satellite cooperative massive multiple-input multiple-output (MIMO) transmission, where multiple massive-MIMO sa…
A Joint JSCC-Resource Allocation Framework for QoS-Aware Semantic Communication in LEO Satellite-based EO Missions
Hung Nguyen-Kha, Ti Ti Nguyen, Vu Nguyen Ha +3
In Earth observation (EO) missions with Low Earth orbit (LEO) satellites, high-resolution image acquisition generates a massive data volume that poses a significant challenge for t…
Secure Task Offloading and Resource Allocation Design for Multi-Layer Non-Terrestrial Networks
Alejandro Flores, Isabella W. G. da Silva, Vu Nguyen Ha +4
Remote and resource-constrained Internet-of-Things (IoT) deployments often lack terrestrial connectivity for task offloading, motivating non-terrestrial networks (NTNs) with onboar…
Toward a Unified Semantic Loss Model for Deep JSCC-based Transmission of EO Imagery
Ti Ti Nguyen, Thanh-Dung Le, Vu Nguyen Ha +6
Modern Earth Observation (EO) systems increasingly rely on high-resolution imagery to support critical applications such as environmental monitoring, disaster response, and land-us…
Multi-Satellite Multi-Stream Beamspace Massive MIMO Transmission
Yafei Wang, Yiming Zhu, Vu Nguyen Ha +4
This paper studies multi-satellite multi-stream (MSMS) beamspace transmission, where multiple satellites cooperate to form a distributed multiple-input multiple-output (MIMO) syste…
