Abstract:In this paper we present the Acquisition Speed Up Engine (ACSE) algorithm, devised in 2007 by Thales Alenia Space in the framework of studies for the GIRASOLE receiver and implemented by Consorzio Pisa Ricerche. The algorithm is used to fast detect the presence of a CDMA signal in a time/frequency uncertainty domain. This is made possible with a serial/parallel approach and a modified FFT algorithm called Fast Fractional Fourier Transform. The ACSE algorithm solves in a very efficient way the trade-off between… 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.
