A Perception vs. Distortion Perspective on Score-Based Generative Channel Estimation
A new research paper explores the application of score-based generative models in wireless communication, specifically for channel estimation. The study frames this application through the lens of a perception-distortion tradeoff, analyzing when score-matching offers advantages over traditional discriminative learning methods. Numerical results indicate that score-based estimation is beneficial in high predictive uncertainty scenarios, enabling near Bayesian-optimal precoding, while discriminative approaches are more suitable for low predictive uncertainty due to lower complexity.
