Pattern-Coupled Sparse Bayesian Learning for Recovery of Block-Sparse Signals
Pattern-Coupled Sparse Bayesian Learning for Recovery of Block-Sparse Signals
We consider the problem of recovering block-sparse signals whose cluster patterns are unknown a priori. Block-sparse signals with nonzero coefficients occurring in clusters arise naturally in many practical scenarios. However, the knowledge of the block partition is usually unavailable in practice. In this paper, we develop a new sparse Bayesian …
