摘要
在介绍小波变换概念及信号奇异性理论分析的基础上,给出了利用小波系数模极大值对信号奇异点判定的算法,并结合仿真试验对小波分析在信号奇异点上的判定进行了分析,效果良好。
On the basis of introducing the concept of wavelet transform and the theory of signal singularity, the algorithm of using wavelet modulus maxima to determine the singular points of signals was presented. And according to the resuh of the simulation experiment, the algorithm was effective for determination of signal singularity based on wavelet anal ysis.
