Spatio-Temporal Reconstruction for Dynamic Radio Maps with Sparse Sampling

Dynamic spectrum access and network optimization require accurate real-time radio maps in urban environments. However, high-density measurements are impractical, and extremely sparse sampling leads to poor reconstruction, particularly when mobile transmitters cause hotspot drift. This paper proposes a spatio-temporal r...

Amortized Neural SVD for XL-MIMO: Structure-Guided Factor Prediction for Beamforming and Multi-Stream Utility

Experiments show that the proposed approach achieves spectral efficiency close to exact SVD-based beamforming in single-stream transmission and consistently improves multi-stream sum-rate over representative learned baselines, indicating good scalability for low-latency wireless processing.
