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 Beamforming Design and Resource Allocation for IRS-Assisted Full-Duplex Terahertz Systems
Chi Qiu, Wen Chen, Qingqing Wu +4
Intelligent reflecting surface (IRS)-assisted full-duplex (FD) terahertz (THz) communication systems have emerged as a promising paradigm to satisfy the escalating demand for ultra…
Dual-Scale Channel Estimation in Sensing-Assisted Communication Systems: Joint Time Allocation and Beamforming Design
Bai Zhiyue, Dai Minghui, Hou Fen +4
In this paper, we propose a novel integrated sensing and communication (ISAC)-enabled dual-scale channel estimation framework, where large-scale channel estimation benefits from se…
Freshness-aware Resource Allocation for Non-orthogonal Wireless-powered IoT Networks
Yunfeng Chen, Yong Liu, Jinhao Xiao +3
This paper investigates a wireless-powered Internet of Things (IoT) network comprising a hybrid access point (HAP) and two devices. The HAP facilitates downlink wireless energy tra…
Intelligent Reflecting Surface Empowered Self-Interference Cancellation in Full-Duplex Systems
Chi Qiu, Meng Hua, Qingqing Wu +5
Compared with traditional half-duplex wireless systems, the application of emerging full-duplex (FD) technology can potentially double the system capacity theoretically. However, c…
