Optimal Uplink Pinching-Antenna Activation
Zhenqiao Cheng, Chongjun Ouyang
An uplink multiuser pinching-antenna system (PASS) is considered, where multiple dielectric waveguides are deployed at the base station and one pinching antenna (PA) is activated o…
Fast Pinching-Antenna Activation for AirComp
Zhenqiao Cheng, Boqun Zhao, Chongjun Ouyang +1
A pinching-antenna system (PASS) is considered for over-the-air computation (AirComp). Multiple dielectric waveguides are deployed at the base station, and one pinching antenna (PA…
Beamforming Gain with Single-RF Movable Arrays
Zhenqiao Cheng, Chongjun Ouyang, Hao Jiang +2
A single-radio-frequency (RF) movable array is investigated, in which all movable elements are driven by a single RF chain with equal amplitude and equal phase. The achievable beam…
Joint Segment Activation and Antenna Placement for Uplink SWAN Systems
Songnan Gu, Zhenqiao Cheng, Hao Jiang +3
This article analyzes the achievable sum-rate of multiuser uplink segmented waveguide-enabled pinching-antenna systems (SWANs). To unveil system-design insights, an upper bound on…
Secure Multiuser Beamforming With Movable Antenna Arrays
Zhenqiao Cheng, Chongjun Ouyang, Boqun Zhao +1
A movable antenna (MA)-enabled secure multiuser transmission framework is developed to enhance physical-layer security. Novel expressions are derived to characterize the achievable…
