Orthogonal Matching Pursuit with Tikhonov and Landweber Regularization
The Orthogonal Matching Pursuit (OMP) for compressed sensing iterates over a scheme of support augmentation and signal estimation. We present two novel matching pursuit algorithms with intrinsic regularization of the signal estimation step that do not rely on a priori knowledge of the signal's sparsity.

2D Orthogonal Matching Pursuit for Fully Polarimetric SAR Image Formation
Fully polarimetric SAR provides richer scattering information than single-polarisation imaging, but multichannel sparse image formation can be computationally and memory demanding, especially when channels are processed jointly.

Joint sparse channel estimation based on angle domain and delay domain
For the channel estimation problem of multiple input multiple output(MIMO) systems in doubly-selective (DS) channels and the joint sparse characteristic in the delay domain and angle domain,a new joint sparse channel estimation scheme based on ...

Sparse Recovery With Orthogonal Matching Pursuit Under RIP [PDF]
This paper presents a new analysis for the orthogonal matching pursuit (OMP) algorithm. It is shown that if the restricted isometry property (RIP) is satisfied at sparsity level $O(\bar{k})$, then OMP can recover a $\bar{k}$-sparse signal in 2-norm. For compressed sensing applications, this result implies that in order to uniformly recover a $\bar{k ...

Recuperación de señales dispersas utilizando orthogonal matching pursuit (OMP)
Muestreo compresivo es una rama emergente del procesamiento de señales, basada en el hecho de que un número pequeño de proyecciones lineales no adaptativas sobre una señal compresible contiene suficiente información para reconstruirla y proce- sarla.

On efficiency of Orthogonal Matching Pursuit
We show that if a matrix $Φ$ satisfies the RIP of order $[CK^{1.2}]$ with isometry constant $\dt = c K^{-0.2}$ and has coherence less than $1/(20 K^{0.8})$, then Orthogonal Matching Pursuit (OMP) will recover $K$-sparse signal $x$ from $y=Φx$ in at most $[CK^{1.2}]$ iterations. This result implies that $K$-sparse signal can be recovered via OMP by $M=O(
