| 摘 要： | 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．应用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，从而对随机信号和混沌信号加以识别．对新的G－P改进算法进一步分析表明：新的G－P改进算法适用范围广泛，对于混沌信号的识别很有效．

| Abstract: | In order to overcome the shortcoming of the G-P algorithm and its improved form, a new approved algorithm has been proposed. When the new algorithm is used, the determination of the no-scale interval is simplified and the judgement for the saturation of the correlation dimension is realized objectively. It isvery efficient for the identification of chaotic signal. Based on the new G-P algorithm, further discussion and analysis about the new G-P algorithm is cAned out. The simulation results show that the applicable range of the new algorithm is very wide. |
