Abstract

In this article, it is proposed by using the empirical mode decomposition and the collection of empirical mode decomposition to decompose the signal and white noise to avoid patterns confused ideas of known frequency signal extraction method .In order to solve the known frequency signal extraction method, some of the problems faced in the extremum point positioning, such as the determination of amplitude, joining the white noise variance, and so on.
