Abstract:Non‐binary turbo codes (TCs) have become an important class of TCs following the adoption of duo‐binary TCs (DBTCs) in the digital video broadcasting with return channel via satellite (DVB‐RCS) standard. Several hierarchical modulation (HM) schemes for binary TCs have been proposed with a view to enhancing their performance. However, the existing techniques make use of fixed parameters throughout the Eb/N0 range and have not been applied to non‐binary TCs. In this paper, optimum parameters have been derived fr… 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.
