Spatial-Code-Domain Grouped Index Modulation: Fluid-Antenna-Assisted System Design and BER Performance Analysis
Peng Zhang, Jian Dang, Yao Ge +5
Fluid antenna systems (FASs) provide reconfigurable spatial resources within compact apertures. In this paper, we introduce code-domain grouped index modulation (CGIM) and its spat…
Code-Domain Grouped Index Modulation for Spectrally Efficient Spread-Spectrum Communications
Peng Zhang, Jian Dang, Zaichen Zhang
Efficient exploitation of spreading resources is important for improving the transmission efficiency of spread-spectrum communications. Code index modulation (CIM) conveys addition…
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 Array-Inspired Location-Posterior-Driven Subarray Sizing and Power Control for Two-Hop AF UAV Relaying
Xuanyi Zhu, Jian Dang, Chen Zhao +2
This paper develops fluid antenna array (FAA)-inspired subarray sizing and transmit-power design for a two-hop amplify-and-forward (AF) unmanned aerial vehicle (UAV) relay using pr…
Off-Grid Position Optimization under Mutual Coupling in Fluid Antenna Arrays
Jingyuan Xu, Jian Dang, Zaichen Zhang
Fluid antenna arrays exploit continuous antenna repositioning within a finite aperture to provide geometry diversity beyond grid-constrained port selection. Every displacement, how…
Sparse Port Selection under Mutual Coupling in Fluid Antenna Arrays
Jingyuan Xu, Haoyu Liang, Zaichen Zhang +1
Fluid antenna systems obtain spatial degrees of freedom by reconfiguring antenna positions within a confined region, a principle that extends to beamforming: shaped beams can be sy…
Fluid-Antenna-Aided Active User Detection With 1D-CNN Channel Reconstruction for Unsourced Random Access
