摘　　要：现有的拍波与调幅波的识别方法存在不足,本文提出了基于分形几何原理的辅助判别方法。仿真及工程实例表明:通过计算时间序列信号的关联维数并根据其值的大小能辅助判断信号的类别。The traditional methods for identifying beat wave and amplitude modulation wave are shortage. The main disadvantage of these methods is that they can＇ t correctly identify in some cases. This paper discusses an assistant method based on fractal geometry theory, which helps to identify the classification of a time serial signals by calculating the correlation dimension of the signals. Simulation and experiments show the results are satisfactory.
