Compressed Sensing with coherent tight frames via $l_q$-minimization for $0<q\leq1$
Our aim of this article is to reconstruct a signal from undersampled data in the situation that the signal is sparse in terms of a tight frame. We present a condition, which is independent of the coherence of the tight frame, to guarantee accurate recovery of signals which are sparse in the tight frame, from undersampled data with minimal l1-norm of transform coefficients. This improves the res...
متن کاملBlock-sparse compressed sensing: non-convex model and iterative re-weighted algorithm
Compressed sensing is a new sampling technique which can exactly reconstruct sparse signal from a few measurements. In this article, we consider the blocksparse compressed sensing with special structure assumption about the signal. A novel non-convex model is proposed to reconstruct the block-sparse signals. In addition, the conditions of the proposed model for recovering the block-sparse noise...
متن کاملBalanced Sparse Model for Tight Frames in Compressed Sensing Magnetic Resonance Imaging
Compressed sensing has shown to be promising to accelerate magnetic resonance imaging. In this new technology, magnetic resonance images are usually reconstructed by enforcing its sparsity in sparse image reconstruction models, including both synthesis and analysis models. The synthesis model assumes that an image is a sparse combination of atom signals while the analysis model assumes that an ...
متن کاملCompressed sensing of block-sparse positive vectors
In this paper we revisit one of the classical problems of compressed sensing. Namely, we consider linear under-determined systems with sparse solutions. A substantial success in mathematical characterization of an l1 optimization technique typically used for solving such systems has been achieved during the last decade. Seminal works [4, 18] showed that the l1 can recover a so-called linear spa...
متن کاملApproximate equiangular tight frames for compressed sensing and CDMA applications
Performance guarantees for recovery algorithms employed in sparse representations, and compressed sensing highlights the importance of incoherence. Optimal bounds of incoherence are attained by equiangular unit norm tight frames (ETFs). Although ETFs are important in many applications, they do not exist for all dimensions, while their construction has been proven extremely difficult. In this pa...
