Pinching-Antenna Enabled Multicell Wireless Systems
Yunshu Chen, Qing Xue, Meng Hua +2
Pinching antenna (PA) systems have recently emerged as a promising flexible-antenna technology, which can reconstruct the wireless propagation environment by dynamically adjusting…
Delay-Doppler Domain Channel Estimation: What if Sparsity is Unknown?
Zijian Yang, Yulin Shao, Fen Hou +1
Sparsity in the delay-Doppler (DD) domain enables efficient channel estimation, but the realization-wise sparsity level is rarely known in advance, and it fluctuates. What if we co…
Multi-Mode Pinching-Antenna Systems: Polarization-Aware Full-Wave Modeling and Optimization
Dengke Wei, Runxin Zhang, Yulin Shao +2
Millimeter-wave and terahertz communications face a fundamental challenge: overcoming severe path loss without sacrificing spectral efficiency. Pinching antenna systems (PASS) addr…
Joint Active and Passive Beamforming with Sensing-Assisted Discrete Phase Shifts for Dual-RIS ISAC Systems
Qing Xue, Yun Lan, Jiajia Guo +2
Targeting the requirements of 6G, this paper investigates a semi-passive dual-reconfigurable intelligent surface (RIS)-assisted integrated sensing and communication (ISAC) system,…
When Feedback Empowers the Uplink: Integrating Adaptive Coding with Wireless Power Transfer
Zijian Yang, Yulin Shao, Shaodan Ma
Energy consumption and device lifetime are critical concerns for battery-constrained IoT devices. This paper introduces the Feedback-Aided Coding and Energy Transfer (FACET) framew…
Power Allocation for Coordinated Multi-Point Aided ISAC Systems
Jianpeng Zou, Zhanfeng Zhong, Jintao Wang +3
In this letter, we investigate a coordinated multiple point (CoMP)-aided integrated sensing and communication (ISAC) system that supports multiple users and targets. Multiple base…
