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…
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…
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…
Optimal Analog Beamforming and Power Allocation for Multiuser TDMA Systems
Songnan Gu, Chongjun Ouyang, Hao Jiang +1
The joint design of analog beamforming and power allocation is investigated for a single radio-frequency chain multiuser time-division multiple access system under a max-min signal…
Pinching Antennas for Multiple Access in Multigroup Multicast Communications
Shan Shan, Chongjun Ouyang, Yong Li +1
This paper aims to design multiple access (MA) schemes to improve the max-min fairness (MMF) for pinching antennas (PAs)-based multigroup multicast communications, where PA placeme…
On the Performance of Tri-Hybrid Beamforming Using Pinching Antennas
Zhenqiao Cheng, Chongjun Ouyang, Nicola Marchetti
The Pinching-Antenna System (PASS) reconfigures wireless channels through \emph{pinching beamforming}, in which the active positions of pinching antennas (PAs) along dielectric wav…
