Low-complexity tuning of pinching-antenna systems for integrated sensing and communication
Saba Asaad, Chongjun Ouyang, Zhiguo Ding +1
Pinching antenna systems (PASSs) can dynamically adapt their transmit and receive arrays for sensing and communication in wireless systems. This work explores the potential of PASS…
Two-Stage Heterogeneous Graph Neural Network for RIS-Aided Physical-Layer Security
Zihan Song, Yang Lu, Wei Chen +3
This paper investigates physical-layer security (PLS) enabled by graph neural networks (GNNs). We propose a two-stage heterogeneous GNN (HGNN) to maximize the secrecy energy effici…
NOMA Assisted Downlink Power Allocation in Pinching Antenna Systems Using Convolutional Neural Network
Saeed Mohammadzadeh, Kanapathippillai Cumanan, Zhiguo Ding
In this paper, we consider a flexible-antenna architecture, referred to as a pinching-antenna (PA) system, in which multiple PAs realized by activating small dielectric particles a…
Deep Learning Optimization of Two-State Pinching Antennas Systems
Odysseas G. Karagiannidis, Victoria E. Galanopoulou, Panagiotis D. Diamantoulakis +2
The evolution of wireless communication systems requires flexible, energy-efficient, and cost-effective antenna technologies. Pinching antennas (PAs), which can dynamically control…
