Expected RIP: Conditioning of The Modulated Wideband Converter
Moshe Mishali, Yonina C. Eldar
The sensing matrix of a compressive system impacts the stability of the associated sparse recovery problem. In this paper, we study the sensing matrix of the modulated wideband con…
The Cramer-Rao Bound for Sparse Estimation
Zvika Ben-Haim, Yonina C. Eldar
The goal of this paper is to characterize the best achievable performance for the problem of estimating an unknown parameter having a sparse representation. Specifically, we consid…
Average Case Analysis of Multichannel Sparse Recovery Using Convex Relaxation
Yonina C. Eldar, Holger Rauhut
In this paper, we consider recovery of jointly sparse multichannel signals from incomplete measurements. Several approaches have been developed to recover the unknown sparse vector…
Efficient Sampling of Sparse Wideband Analog Signals
Moshe Mishali, Yonina C. Eldar, Joel A. Tropp
Periodic nonuniform sampling is a known method to sample spectrally sparse signals below the Nyquist rate. This strategy relies on the implicit assumption that the individual sampl…
