Fluid-Antenna-Assisted Distributed Joint Decoding for Cell-Free Massive MIMO Unsourced Random Access
Liandong Hu, Jian Dang, Zaichen Zhang
Unsourced random access (URA) supports massive sporadic connectivity but remains limited by multiuser interference, distributed channel uncertainty, and local fading. This paper pr…
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…
