Fluid-Antenna-Aided Active User Detection With 1D-CNN Channel Reconstruction for Unsourced Random Access
Haoyu Liang, Zhentian Zhang, Hao Jiang +2
In this paper, we investigate the application of fluid antenna systems (FAS) for active user detection (AUD) in unsourced random access (URA). A channel reconstruction method based…
Fluid Antenna-assisted Unsourced ISAC Massive Access
Jingyuan Xu, Zhentian Zhang, Hao Jiang +2
Unsourced integrated sensing and communication (UNISAC) has emerged as a promising paradigm for supporting massive connectivity in 6G networks. However, existing approaches predomi…
Artificial-Noise-Aided Secure Near-Field MIMO With Fluid Antenna Systems
Peng Zhang, Jian Dang, Miaowen Wen +5
With the evolution of mobile communication systems toward large-scale arrays, high-frequency operation, and reconfigurable antenna architectures, fluid antenna systems (FAS) operat…
Fluid Reconfigurable Intelligent Surface Enabling Index Modulation
Peng Zhang, Jian Dang, Miaowen Wen +5
Fluid reconfigurable intelligent surfaces (FRIS) enable joint position and phase reconfigurability by integrating fluid antennas (FA) with conventional reconfigurable intelligent s…
Fundamental Tradeoffs for ISAC Multiple Access in Finite-Blocklength Regime
Zhentian Zhang, Christos Masouros, Kai-Kit Wong +5
This paper investigates the fundamental communication--sensing tradeoffs of uplink dual-functional integrated sensing and communication (ISAC) multiple access under finite blocklen…
Iterative Gaussian Approximation for Random Spreading Unsourced Random Access
Liandong Hu, Jian Dang, Zaichen Zhang
Massive machine-type communications (mMTC) demand robust solutions to support extensive connectivity efficiently. Unsourced random access (URA) has emerged as a promising approach,…
