State evolution for general approximate message passing algorithms, with applications to spatial coupling
Year: 2013
Type: article
Abstract: We consider a class of approximated message passing (AMP) algorithms and characterize their high-dimensional behavior in terms of a suitable state evolution recursion. Our proof applies to Gaussian matrices with independent but not necessarily identically distributed entries. It covers—in particular—the analysis of generalized AMP, introduced by Rangan, and of AMP reconstruction in compressed sensing with spatially coupled sensing matrices. The proof technique builds on that of Bayati & Montanari [2], while simplifying and generalizing several steps.
