HAP-Centric Flying Ad-Hoc Networks With Cell-Free Non-Terrestrial Connectivity
Muhammet Kırık, Liza Afeef, Halim Yanikomeroglu +1
High-altitude platforms (HAPs) are key enablers of next-generation non-terrestrial networks (NTNs), offering wide coverage, long endurance, and rapid deployment. Despite these adva…
PHY Authentication for Ambient IoTs in Near-Field XL-MIMO Backscatter Communication Systems
Fikiri Salum Uledi, Hafsa Ahmad, Muhammad Bilal Janjua +2
This letter exploits near-field (NF) spherical wavefronts to derive geometry-dependent physical signatures for backscatter device (BD) authentication in extremely large-scale multi…
Energy-Efficient Target-Aware Hybrid Beamforming for THz Near-Field ISAC with Sparse Connectivity
Nusaibah A. Alshorman, Chong Han, Huseyin Arslan
Integrated sensing and communication (ISAC) at terahertz (THz) frequencies enables ultra-high-resolution perception while facing a key limitation: highly directional THz beams cann…
Posterior-Confidence Driven Beamforming for Energy-Efficient Integrated Sensing and Communication
Nusaibah A. Alshorman, Huseyin Arslan
The paper proposes an energy‑efficient MIMO beamforming framework for integrated sensing and communication that activates sensing only when needed, using posterior confidence and n…
Scalable Multi-BD Access for OFDM-Based Symbiotic Backscatter Communications
Fikiri Salum Uledi, Muhammad Bilal Janjua, Muhammad Sohaib J. Solaija +2
The paper proposes a scheme that lets multiple backscatter devices communicate simultaneously with an OFDM transmitter by reserving empty subcarriers and assigning orthogonal codew…
ISAC with Affine Frequency Division Multiplexing: An FMCW-Based Signal Processing Perspective
Jiajun Zhu, Yanqun Tang, Cong Yi +5
This paper investigates the sensing potential of affine frequency division multiplexing (AFDM) in high-mobility integrated sensing and communication (ISAC) from the perspective of…
