Abstract:Abstract. This paper presents the variance analysis, and performance comparison, of the leastsquares frequency estimator (LSFE), and a specific version of the nonlinear frequency estimator (NIX). The results are obtained for the case where the received signal contains both phase and frequency errors (A0 and Afrespectively). It is shown that under rather restrictive conditions, the LSFE is a low signal-to-noise ratio approximation to the ML estimate of Af Also considered are the effects on the moments of this e… 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.
