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…
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…
User Tracking and Direction Estimation Codebook Design for IRS-Assisted mmWave Communication
Moritz Garkisch, Sebastian Lotter, Gui Zhou +2
Future communication systems are envisioned to employ intelligent reflecting surfaces (IRSs) and the millimeter wave (mmWave) frequency band to provide reliable high-rate services.…
