Security-Aware Pinching-Antenna Systems (PASS): Physical-Layer Security Transmission
Zhaoming Hu, Xiaochen Nie, Ruikang Zhong +3
This paper investigates heterogeneous secure multi-user transmission in pinching-antenna systems (PASS), where dynamically adjustable pinching antennas reshape both guided-wave and…
Beamforming Design for Pinching Antenna Systems Enabled Cognitive Radio Systems
Haochen Li, Ruikang Zhong, Zhaoming Hu +3
A pinching antenna system (PASS) assisted cognitive radio (CR) system is proposed. A secondary system sum rate maximization problem is formulated by jointly considering the base st…
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…
Graph-Enhanced LLM for SWAN-ISAC
Qian Gao, Ruikang Zhong, Yuanwei Liu
Segmented pinching antenna assisted integrated sensing and communication (ISAC) systems enable flexible spatial resource utilization by allowing different waveguide segments to be…
Waveform Design for Partial-Time Superimposed ISAC Systems
Xi Nan, Rugui Yao, Ye Fan +4
Nowadays, waveforms of integrated sensing and communication (ISAC) are almost based on conventional communication and sensing signal, which bounds both the communication and sensin…
Deep Learning based Three-stage Solution for ISAC Beamforming Optimization
Qian Gao, Ruikang Zhong, Yuanwei Liu
In this paper, a general ISAC system where the base station (BS) communicates with multiple users and performs target detection is considered. Then, a sum communication rate maximi…
