CMT-Aware Channel Modeling and Transmit-Power Minimization for Pinching-Antenna Systems
Chuang Luo, Gui Zhou, Vasilis K. Papanikolaou +2
This letter investigates transmit-power minimization for multiuser pinching-antenna system (PAS) from a coupled-mode-theory (CMT)-aware perspective. Existing CMT-based pinching ant…
V-RIS: Virtual-Aperture DoA Estimation with Sparse RIS
Fenghao Zheng, Fuhai Wang, Zihan Jin +3
The paper introduces V-RIS, a method that uses only four corner subarrays of a reconfigurable intelligent surface and a single-antenna receiver to reconstruct a virtual‑aperture su…
Energy-Efficient Design for Downlink Pinching-Antenna Systems with QoS Guarantee
Ming Zeng, Ji Wang, Gui Zhou +2
Pinching antennas have recently garnered significant attention due to their ability to dynamically reconfigure wireless propagation environments. Despite notable advancements in th…
Resolving the Double Near-Far Problem via Wireless Powered Pinching-Antenna Networks
Vasilis K. Papanikolaou, Gui Zhou, Brikena Kaziu +4
This letter introduces a novel wireless powered communication system, referred to as a wireless powered pinching-antenna network (WPPAN), utilizing a single waveguide with pinching…
Channel Estimation for mmWave Pinching-Antenna Systems
Gui Zhou, Vasilis Papanikolaou, Zhiguo Ding +1
The full potential of pinching-antenna systems (PAS) can be unblocked if pinching antennas can be accurately activated at positions tailored for the serving users', which means tha…
