Coherence-Based Performance Guarantees of Orthogonal Matching Pursuit
Compressive Sensing(CS) Orthogonal Matching Pursuit(OMP) worst-case coherence average coherence support recovery signal reconstruction
2012/11/23
In this paper, we present coherence-based performance guarantees of Orthogonal Matching Pursuit (OMP) for both support recovery and signal reconstruction of sparse signals when the measurements are co...
Coherence-Based Performance Guarantees for Estimating a Sparse Vector Under Random Noise
Coherence-Based Performance Guarantees Sparse Vector Random Noise
2010/3/19
We consider the problem of estimating a deterministic
sparse vector x0 from underdetermined measurements
Ax0 + w, where w represents white Gaussian noise and A is
a given deterministic dictionary. ...
