Abstract:Abstract-Designing perfect-reconstruction orthogonal cosinemodulated filter banks is essentially a nonconvex problem and to date only local solutions can be claimed. By virtue of the recent progress in global polynomial optimization, this paper describes an attempt of developing a global design method using an orderrecursive strategy combined with a technique that identifies a desirable initial point in each round of recursion. Simulation and comparison studies are presented to evaluate the performance of the … 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.
