Denoising and Augmentation: A Dual Use of Diffusion Model for Enhanced CSI Recovery

2025 · arXiv (Cornell University)

This letter introduces a dual application of denoising diffusion probabilistic model (DDPM)-based channel estimation algorithm integrating data denoising and augmentation. Denoising addresses the severe noise in raw signals at pilot locations, which can impair channel …
