A modified variable step‐size affine projection sign algorithm (MVSS‐APSA) is proposed. Considering the effect of the noise on the steady‐state error, the first moment estimation of the noise is utilised to modify the variable step‐size update. The test on system identifications under an impulsive noise environment shows that the proposed MVSS‐APSA has lower steady‐state misalignment than the VSS‐APSA.
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.
