Independent Component Analysis in Chaotic Signal Analysis
Yin Li · Dianzi xuebao · 2002
We try to explore the higher order statistics information of chaotic system in this paper,and introduce a new blind signal separation method,independent component analysis,into chaotic signal processing.Firstly,we proposed a new method to search the optimum delay of phase space reconstruction,then we estimated the local intrinsic dimension from independent component analysis.The corresponding experiments showed good results,more interestingly,the latter method can distinguish between a 1/ f process and a chaotic system.
