6DMA-FIM-Enabled User-Centric Cell-Free Massive MIMO With Two-Layer RSMA

This paper proposes a novel user-centric (UC) cell-free massive MIMO (CF-mMIMO) architecture empowered by six-dimensional movable antennas (6DMA) and flexible intelligent metasurfaces (FIM), integrated with a two-layer rate-splitting multiple access (RSMA) framework. Unlike conventional fixed-position deployments, the...

Sparse Channel Acquisition in Aging Fluid Antenna Systems: A Reliability-Calibrated Posterior Reconstruction Approach

Fluid antenna systems (FASs) exploit port-domain diversity within a compact aperture, but their gain can be lost if the receiver has to scan too many ports before data transmission. This paper studies sparse channel acquisition for aging FAS receivers, where the available information has mixed reliability: current obse...

Disentangling Dual-Polarized Channel Representations for Accurate User Localization

Indoor localization has emerged as a critical enabling technology for various smart applications, yet its performance is constrained by multipath propagation, signal blockage, and environmental dynamics. While recent deep learning (DL)-based approaches have demonstrated promising improvements over traditional technique...

A Confidence-Aware Semi-Supervised Learning Framework for Automatic Modulation Recognition

Automatic modulation recognition (AMR) is a cornerstone of dynamic spectrum allocation and cognitive radio. Despite the promise of deep learning-based methods, their reliance on large labeled datasets limits their practicality in scenarios with scarce labeled samples. To address this, we propose a confidence-aware semi...

Block-Correlation-Based Outage Analysis for FAS-Assisted Wireless Powered Communication

A fluid antenna system (FAS) can improve both energy harvesting and data transmission in wireless powered communication (WPC) by exploiting spatial diversity with a single RF chain. In this letter, we study the outage probability of a FAS-assisted WPC network under the port selection criterion that maximizes the produc...
