LOSSY SOURCE CODING FOR NON-UNIFORM SOURCES USING LDGM CODES
Abstract
Recently low-density generator matrix (LDGM) codes along with various message-passing algorithms (e.g., survey propagation algorithm) have been used for lossy source coding. In contrast with most prior work which has focused exclusively on uniformly distributed sources, we address the problem of lossy coding for sources with arbitrary distributions. Built upon the idea of approximating the optimal output distribution indicated by the …
