Abstract:This paper deals with code-aided (CA) maximumlikelihood (ML) phase and timing ambiguity resolution. We propose a methodology based on the sum-product algorithm (SPA) to exactly solve this problem with a tractable complexity. In particular, we emphasize that the proposed ML ambiguityresolution algorithm has a complexity which is at most equal to the complexity of recently-proposed powerful ML-like ambiguityresolution methods. Finally, we compare through simulation results the ability of CA and conventional data… 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.
