An Improved Method of Extracting the Correlation Dimension from a Chaotic Signal
-
摘要: 相關(guān)維是描述混沌信號的一個重要參數(shù),論文對相關(guān)維提取算法進行了深入的研究,結(jié)合流行的GP算法給出了一種提取相關(guān)維的改進算法。該算法具有運算量小、精度高、尺度選擇盲目性小等特點。

Abstract: The correlation dimension is an important parameter for describing a chaotic signal. The method of extracting the correlation dimension is deeply researched in this paper. Based on the GP method, an improved algorithm of extracting the correlation dimension is given. The algorithm has the character of little calculating amount, higher accuracy and smaller aimless ability of scaling selection. -
