Abstract:In this paper, we propose a semiblind multiuser detection framework for asynchronous CDMA. Compared with most existing semiblind/blind detectors, the proposed framework requires a minimum number of previously received signals, which is about the number of interfering signals, and no detection filter converging or subspace separation procedure. The computational complexity and detection delay are therefore much lower. In this framework, a semiblind multiuser signal model is used instead of the widely-discussed … 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.
