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…
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…
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…
Low-complexity tuning of pinching-antenna systems for integrated sensing and communication
Saba Asaad, Chongjun Ouyang, Zhiguo Ding +1
Pinching antenna systems (PASSs) can dynamically adapt their transmit and receive arrays for sensing and communication in wireless systems. This work explores the potential of PASS…
