Coherence-Based Performance Guarantees for Estimating a Sparse Vector Under Random Noise
Zvika Ben-Haim, Yonina C. Eldar, Michael Elad
We consider the problem of estimating a deterministic sparse vector x from underdetermined measurements Ax+w, where w represents white Gaussian noise and A is a given deterministic…
