Sparse signal recovery in the presence of colored noise and rank-deficient noise covariance matrix: An SBL approach

In this work, we address the recovery of sparse and compressible vectors in the presence of colored noise possibly with a rank-deficient noise covariance matrix, from overcomplete noisy linear measurements. We exploit the structure of the noise covariance matrix in a Bayesian framework. In particula…
