摘要
从广泛的意义上分析了混沌动力学系统和噪声的局部相关性 ,并由此提出了一种分析信号确定性的方法 ,导出一个对噪声极其敏感的指示参数D ,并用此参数来刻划系统确定性的程度 .
On the basis of the extensive analysis of the local correlation with the chaotic dynamic system, a method for analyzing 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 method for Estimation of Noise Distribution in chaotic distribution system is obtained.
