Joint Beamforming, Energy Management, and Trajectory Optimization for Figure-Eight Loitering in Solar-Powered HAPS-Enabled ISAC Systems
Xue Zhang, Bang Huang, Mohamed-Slim Alouini
The paper proposes a solar‑powered high‑altitude platform station (HAPS) framework that uses a figure‑eight loitering pattern to provide continuous integrated sensing and communica…
CRB-Based Resource Allocation in Multi-User Uplink Transmissions
Xue Zhang, Abla Kammoun, Mohamed-Slim Alouini
In this work, we study the design of receivers for uplink multi-user systems, aiming to estimate both the channel and the transmitted symbols. We consider two estimation strategies…
Toward Environment-Aware LAE: SAR as a Shared Sensing Infrastructure
Xue Zhang, Bang Huang, Mohamed-Slim Alouini
The rapid growth of the low-altitude economy (LAE) is making aerial systems an important part of future digital infrastructure. Although major advances have been achieved in unmann…
Design of 3D Beamforming and Deployment Strategies for ISAC-based HAPS Systems
Xue Zhang, Bang Huang, Mohamed-Slim Alouini
This paper explores high-altitude platform station (HAPS) systems enabled by integrated sensing and communication (ISAC), in which a HAPS simultaneously transmits communication sig…
Fundamental limits via CRB of semi-blind channel estimation in Massive MIMO systems
Xue Zhang, Abla Kammoun, Mohamed-Slim Alouini
This paper investigates the asymptotic behavior of the deterministic and stochastic Cramér-Rao Bounds (CRB) for semi-blind channel estimation in massive multiple-input multiple-ou…
