Let $p$ be an input distribution and let $\mathbf W$ denote the channel model. Write $\overline{\mathcal{R}}(p,\mathbf W)$ for the distortion achieved uniformly over the input dist…

Universal denoising conjecture. Under some technical conditions, the modified universal denoiser achieves the MMSE asymptotically for unbounded stationary ergodic signals.

Let the input signal be a stationary ergodic signal, and let the proposed universal denoiser use context quantization together with Gaussian-mixture model learning, without requiri…
