C-PASS: Center-Fed Pinching Antenna System
Xu Gan, Yuanwei Liu
A novel architecture of the center-fed pinching antenna system (C-PASS) is proposed. In contrast to the conventional end-fed PASS, signals are fed from the center input ports and p…
Bridging Standardized Codebook and Site-Specific Beamforming: A Unified Limited-Feedback Framework
Cheng-Jie Zhao, Zhaolin Wang, Zongyao Zhao +1
A site-specific Type-II codebook design is proposed for downlink massive multiple-input multiple-output (MIMO) limited-feedback beamforming. The key idea is to embed a learned site…
Cramér-Rao Bound Optimization for Near-Field ISAC with Extended Targets
Zongyao Zhao, Zhaolin Wang, Lincong Han +4
Near-field integrated sensing and communication (ISAC) requires target models beyond the point-target abstraction when the target has a non-negligible spatial extent. In this lette…
Mobile Communications in Intelligent Rail Transit: From LCX to PASS
Yiran Guo, Wei Chen, Cong Yu +3
Wireless communications in intelligent rail transit face harsh propagation conditions, including severe penetration loss, frequent blockages, and amplified large-scale fading. Exis…
Mutual Coupling-Aware Beamforming in Multi-User Continuous Aperture Array Systems
Junjie Ye, Zhaolin Wang, Yuanwei Liu +3
A mutual coupling-aware beamforming design for continuous aperture array (CAPA)-aided multi-user systems is investigated. First, a transmit coupling kernel is characterized to expl…
LLM-enabled Antenna Partitioning and Beamforming Optimization for Segmented Pinching
Qian Gao, Ruikang Zhong, Hyundong Shin +1
Integrated sensing and communication (ISAC) requires spatial architectures that can flexibly balance data transmission and environment sensing. Segmented pinching antenna-assisted…
