摘要
介绍了小波变换的基本理论、奇异信号的特性及小波变换用于奇异信号检测的基本原理.并在Mat-lab下进行奇异信号的仿真试验,取得了理想的效果.实验结果表明,小波变换在奇异信号的检测中是有效的.
The basic theory of the wavelet transform is introduced. The specialty of singularity signal and the principle of wavelet transform used in singularity signal detection are also described. The simulating experiment of singularity signal based on Matlab obtains the ideal result. It expresses that singularity signal detection based on the wavelet transform is effective.
