摘 要: | 为了识别混沌信号和随机信号,针对G-P算法及其改进算法的不足,提出了一种新的改进算法,该算法不仅能简化无标度区的确定过程,而且能客观地判断系统的关联维数是否饱和,仿真结果表明,新的改进算法对于混沌信号的识别是有效的。

Abstract: | In order to distinguish chaoticsignal from stochastic signal, a new improved algorithm is proposed to overcome theshortcoming of the G-P algorithm and its improved form. The determination of the no-scaleinterval is simplified when the new algorithm is used. Moreover, the judgement for thesaturation of the correlation dimension is realized objectively. The effectiveness of thenew algorithm is illustrated by simulation samples. |
