FM-RME: Foundation Model Empowered Radio Map Estimation

This feed collects recent arXiv preprints (Feb 27, 2026) focused on wireless communications, RF sensing, signal processing, and ML/AI for radio systems. Highlights include: FM-RME, a foundation-model approach for multi-dimensional radio-map estimation with zero-shot inference; CSI-RFF, which extracts stable per-device micro-signals from commodity Wi‑Fi CSI enabling high-accuracy RF fingerprinting (open-set authentication); ClusterCKM and other works improving channel estimation via environment knowledge and X-REFINE, an XAI-driven input-filtering and architecture fine-tuning approach; PAO, a “
