Curved Waveguide-Enabled Pinching-Antenna System (C-PAS): Communication Performance Analysis
Yayun Qu, Kunrui Cao, Tao Wang +5
Existing studies on the pinching-antenna system (PAS) assume that waveguides are deployed straight, which fails to serve communication regions with curved boundaries. To address th…
Vertical Pinching Antenna Systems (V-PAS) Aided UAV Communications
Tao Wang, Kunrui Cao, Yayun Qu +4
To address the limitation that existing horizontal pinching antenna systems (PAS) are primarily designed for ground users and confined to two-dimensional (2D) coverage, this paper…
Secure Wireless-Powered zeRIS Communications
Jingyu Chen, Kunrui Cao, Panagiotis D. Diamantoulakis +4
This paper introduces the concept of wireless-powered zero-energy reconfigurable intelligent surface (zeRIS), and investigates a wireless-powered zeRIS aided communication system i…
Covert Communications in Active-IOS Aided Uplink NOMA Systems With Full-Duplex Receiver
Xueyu Kang, Nan Qi, Lu Lv +3
In this paper, an active intelligent omni-surface (A-IOS) is deployed to aid uplink transmissions in a non-orthogonal multiple access (NOMA) system. In order to shelter the covert…
Dual-Functional Artificial Noise (DFAN) Aided Robust Covert Communications in Integrated Sensing and Communications
Runzhe Tang, Long Yang, Lv Lu +3
This paper investigates covert communications in an integrated sensing and communications system, where a dual-functional base station (called Alice) covertly transmits signals to…
