Abstract:In this paper we consider a class of fully-sourceinvolved low-density parity-check (FSI-LDPC) codes. We show that the code designed based on the conventional bipartite graph may not be feasible or implementable. We investigate the applicability of the bipartite graph as a representation of an FSI-LDPC code for density evolution. We discuss the applicable range of the bipartite representation. Then we introduce tripartite graph for FSI-LDPC codes as a modification of the conventional bipartite representation. I… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
