Prosparse denoise: Prony's based sparse pattern recovery in the presence of noise

Jon Onativia, Yue M. Lu, Pier Luigi Dragotti

ICASSP 2016accepted

We present a novel algorithm - ProSparse Denoise - that can solve the sparsity recovery problem in the presence of noise when the dictionary is the union of Fourier and identity matrices. The algorithm is based on a proper use of Cadzow routine and Prony's method and exploits the duality of Fourier…

Sparsity pattern recovery using FRI methods

Jon Onativia, Yue M. Lu, Pier Luigi Dragotti

ICASSP 2015accepted

The problem of finding the sparse representation of a signal has attracted a lot of attention over the past years. In particular, uniqueness conditions and reconstruction algorithms have been established by relaxing a non-convex optimisation problem. The finite rate of innovation (FRI) theory is an…
