Statistical Mechanical Analysis of Compressed Sensing Utilizing Correlated Compression Matrix (1001.4361v2)
Published 25 Jan 2010 in cs.IT, cond-mat.dis-nn, and math.IT
Abstract: We investigate a reconstruction limit of compressed sensing for a reconstruction scheme based on the L1-norm minimization utilizing a correlated compression matrix with a statistical mechanics method. We focus on the compression matrix modeled as the Kronecker-type random matrix studied in research on multi-input multi-output wireless communication systems. We found that strong one-dimensional correlations between expansion bases of original information slightly degrade reconstruction performance.
