Center-Fed Pinching Antenna System (C-PASS) Aided Wireless Communications
Xu Gan, Yuanwei Liu
The novel architecture of the center-fed pinching antenna system (C-PASS) is investigated, where the waveguide-fed signal is divided into two propagation directions through control…
Sum-Rate Maximization for Uplink Segmented Waveguide-Enabled Pinching-Antenna Systems
Songnan Gu, Hao Jiang, Chongjun Ouyang +2
A multiuser uplink transmission framework based on the segmented waveguide-enabled pinching-antenna system (SWAN) is proposed under two operating protocols: segment selection (SS)…
Robust Beamforming for Pinching-Antenna Systems
Mingjun Sun, Chongjun Ouyang, Shaochuan Wu +1
Pinching-antenna system (PASS) mitigates large-scale path loss by enabling flexible placement of pinching antennas (PAs) along the dielectric waveguide. However, most existing stud…
Learning Beamforming for Pinching Antenna System-Enabled ISAC in Low-Altitude Wireless Networks
Jia Guo, Yuanwei Liu, Arumugam Nallanathan
This work investigates the joint learning of pinching antenna (PA) positions and transmit beamforming for PA-aided integrated sensing and communication (ISAC) in the low-altitude w…
Resource Allocation for Pinching-Antenna Systems (PASS)-enabled NOMA Communications
Songtao Xue, Jingjing Zhao, Kaiquan Cai +3
Pinching-antenna systems (PASS) have emerged as a promising technology due to their ability to dynamically reconfigure wireless propagation environments. A novel PASS-based multi-u…
Directional Pinching-Antenna Systems
Runxin Zhang, Yulin Shao, Yuanwei Liu
We propose a directional pinching-antenna system (DiPASS), a comprehensive framework that transitions PASS modeling from idealized abstraction to physical consistency. DiPASS intro…
