New Identification Method for Chaos (Ⅱ)
-
摘要: 為了識別混沌信號和隨機信號,針對G-P算法及其改進算法的不足,提出了一種新的改進算法.該算法不僅能簡化無標度區的確定過程,而且能客觀地判斷系統的關聯維數是否飽和.仿真結果表明,新的改進算法對于混沌信號的識別是有效的.Abstract: In order to distinguish chaotic signal from stochastic signal, a new improved algorithm is proposed to overcome the shortcoming of the G-P algorithm and its improved form. The determination of the no-scale interval is simplified when the new algorithm is used. Moreover, the judgement for the saturation of the correlation dimension is realized objectively. The effectiveness of the new algorithm is illustrated by simulation samples.
