Radio measurements: The use of the numbers of zero-level crossings to detect a periodicity with known frequency in a noisy signal

Abstract

A method of detecting a periodicity with a known frequency in a noisy signal is proposed, based on a spectral estimate of the numbers of zero-level crossings by a signal and which has low computational costs. The results of investigations, which demonstrate, in principle, the possibility of using the proposed method for practical problems, are presented. © 2013 Springer Science+Business Media New York.
