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…
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…
On the Performance of Physical Layer Security for Continuous-Aperture Array (CAPA) Systems
Boqun Zhao, Chongjun Ouyang, Xingqi Zhang +1
A continuous-aperture array (CAPA)-based secure transmission framework is proposed to enhance physical layer security. Continuous current distributions, or beamformers, are designe…
Continuous-Aperture Array-Based ISAC Over Fading Channels
Boqun Zhao, Chongjun Ouyang, Xingqi Zhang +1
A framework of continuous-aperture array (CAPA)-based integrated sensing and communications (ISAC) under a fading communication channel is proposed. A continuous operator-based sig…
Downlink and Uplink ISAC in Continuous-Aperture Array (CAPA) Systems
Boqun Zhao, Chongjun Ouyang, Xingqi Zhang +2
A continuous-aperture array (CAPA)-based integrated sensing and communications (ISAC) framework is proposed for both downlink and uplink scenarios. Within this framework, continuou…
Performance Analysis of Physical Layer Security: From Far-Field to Near-Field
Boqun Zhao, Chongjun Ouyang, Xingqi Zhang +1
The secrecy performance in both near-field and far-field communications is analyzed using two fundamental metrics: the secrecy capacity under a power constraint and the minimum pow…
