Abstract :
This paper addresses the problem of filtering noise out from a chaotic signal. To pursue this aim, we prefer to estimate noise distribution under chaotic background first. Since chaotic signal has internal random property, it´s hard to filter the noise out with a normal method. On the basis of the extensive analysis of the local correlation of the chaotic dynamic system, a method for analyzing a signal´s deterministic degree is given. A parameter D being very sensitive to the noise is introduced and used to show how deterministic the system is. A new approach for estimation of noise distribution in chaotic distribution system is obtained.
