摘要
阐述了小波变换去除信号噪声的基本原理和方法。研究利用小波变换技术对信号噪声进行抑制和去除非平稳信号的噪声 ,然后利用 Matlab软件编制程序实现了基于小波变换的正弦信号噪声抑制和非平稳信号的去噪仿真分析。仿真结果表明小波变换去除噪声的效果比传统的 Fourior变换方法具有极大的优越性。
Expounding the basic theory and method of removing noises from signals with wavelet transform. Researching to control noises of signals and remove noises from the unsteady signals with the technique of wavelet. And then using Matlab to realize simulation of wavelet denoising by programming. The results indicates that wavelet denoising is more advantaged than the Fourior transform.
