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…
Spatio-Sequential Recurrent Network for 3-D Tunnel Propagation Modeling
Jiahao Li, Jingxin Xue, Keqi Ni +4
Fine-mesh parabolic wave equation (PWE) simulations are high-fidelity but time-consuming, which limits real-time tunnel propagation analysis and motivates coarse-to-fine reconstruc…
A Stable SBP-SAT FDTD Subgridding Method Without Region Split
Yuhui Wang, Langran Deng, Weibo Wu +7
A provably stable summation-by-parts simultaneous approximation term (SBP-SAT) finite-difference time-domain (FDTD) subgridding method without region split is proposed. By designin…
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…
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…
