RadioTrace uses diffusion models for improved radio map estimation

Researchers have developed RadioTrace, a new framework for estimating radio map distributions from sparse wireless signal measurements. This method integrates a pre-trained diffusion model with sparse RSS measurements, crucially incorporating transmitter location estimation directly into the denoising process. RadioTrace also uses a propagation-guided K-means initialization to improve robustness and provides a stability analysis for its transmitter-coordinate refinement component. Experiments show RadioTrace performs competitively with state-of-the-art methods, demonstrating adaptability and robustness for applications like spectrum management and localization. AI

IMPACT This research could improve the accuracy and efficiency of radio map estimation, benefiting applications like spectrum management and localization.
