小波变换在信号奇异性检测中的应用

Wavelet Transform and its Application in the Detection of Signal Singularity

小波变换突破了传统傅里叶变换等信号处理方法的限制,在时域和频域上可同时对信号实现局部化处理,这更符合信号非平稳的变频带结构特征,因而在信号检测奇异性等方面具有广泛的应用价值。本文简要地介绍了小波应用在信号奇异性检测方面变换的基本原理,并通过仿真实验进行了验证。

Unlike traditional Fourier transform,the wavelet transform has good localization property both in time and frequency domains.The application of the wavelet transform in the detection of the singularity is briefly introduced in this paper.Simulation validates is also made.
