摘要
作者在该文中介绍了基于小波变换的信号多分辨率分解，比较了信号和噪声在小波变换下的不同特性，给出了使用小波变换模极大化的信号奇异性检测算法。
This paper introduces a multiresolution decomposition of signals based on their wavelet transform. The different behaviors of the wavelet transform between the signal and the noise are compared. An algorithm for signals singularity detection is proposed by modulus maxima of the wavelet transform.
