A block-iterative parallel decomposition method is proposed to solve general quadratic signal recovery problems under convex constraints. Unlike existing schemes, the proposed method proceeds by local linearizations of blocks of constraints and it is therefore not sensitive to their analytical complexity. Implementation-related issues are discussed and an application to signal deconvolution is demonstrated
