Covert Semantic Transmission in ISAC: Dual-Functional Waveform Design and Rectified Flow-Assisted Recovery
Yunfan Bai, Yuwen Qian, Cheng Zeng +5
The paper proposes CoSMIC, a framework that embeds semantic information into a dual-functional ISAC waveform while maintaining covertness, and introduces a rectified flow refiner t…
Sparse Fluid Antenna Arrays: Continuous Position Design Beyond Classical DOF Limits
Tuo Wu, Jie Tang, Ye Tian +3
Fluid antenna system (FAS), which continuously repositions a single physical element across a deployment region , breaks this limit by freeing antenna positions from the di…
Pinching Antenna Systems (PASS) for Cell-Free Communications
Haochen Li, Jiayi Lei, Cheng Zeng +3
A pinching antenna system (PASS) assisted cell-free communication system is proposed. A sum rate maximization problem under the BS power budget constraint and PA deployment constra…
Channel Estimation for XL-MIMO Systems with Decentralized Baseband Processing: Integrating Local Reconstruction with Global Refinement
Anzheng Tang, Jun-Bo Wang, Yijin Pan +6
In this paper, we investigate the channel estimation problem for extremely large-scale multiple-input multiple-output (XL-MIMO) systems with a hybrid analog-digital architecture, i…
Flexible Rate-Splitting Multiple Access for Near-Field Integrated Sensing and Communications
Jiasi Zhou, Cong Zhou, Cheng Zeng +1
This letter presents a flexible rate-splitting multiple access (RSMA) framework for near-field (NF) integrated sensing and communications (ISAC). The spatial beams configured to me…
