The wavelet transform theory, especially the singularity-detected theory is discussed in this chapter. At last, an algorithm of traveling wave singularity detection using modulus maximum line based on nonlinear threshold de-noising is presented after lots of simulations.
在阐述小波变换理论的基础上，作者重点研究了基于小波变换的奇异点的检测理论，并通过大量的仿真实验，提出了在非线性阈值法滤噪的基础上采用模极大值线的方法来检测行波信号的奇异点。
