The Convergence Guarantees of a Non-convex Approach for Sparse Recovery
Laming Chen, Yuantao Gu
In the area of sparse recovery, numerous researches hint that non-convex penalties might induce better sparsity than convex ones, but up until now those corresponding non-convex al…
On the Performance Bound of Sparse Estimation with Sensing Matrix Perturbation
Yujie Tang, Laming Chen, Yuantao Gu
This paper focusses on the sparse estimation in the situation where both the the sensing matrix and the measurement vector are corrupted by additive Gaussian noises. The performanc…
Quantization Reference Voltage of the Modulated Wideband Converter
Yaming Wang, Laming Chen, Yuantao Gu
The Modulated Wideband Converter (MWC) is a recently proposed analog-to-digital converter (ADC) based on Compressive Sensing (CS) theory. Unlike conventional ADCs, its quantization…
Proof of Convergence and Performance Analysis for Sparse Recovery via Zero-point Attracting Projection
Xiaohan Wang, Yuantao Gu, Laming Chen
A recursive algorithm named Zero-point Attracting Projection (ZAP) is proposed recently for sparse signal reconstruction. Compared with the reference algorithms, ZAP demonstrates r…
Oracle-order Recovery Performance of Greedy Pursuits with Replacement against General Perturbations
Laming Chen, Yuantao Gu
Applying the theory of compressive sensing in practice always takes different kinds of perturbations into consideration. In this paper, the recovery performance of greedy pursuits…
