利用小波对信号去噪,是小波理论应用于实际的一个重要方面。介绍用于一维检测信号去噪的几种常用方法,在Matlab7.0系统仿真工具中实现了去噪算法,并对这几种算法的去噪效果进行了比较。
Using wavelet to denoise the signal is an important aspect of wavelet theory applied in practice. Several commonly used methods for denoising one-dimensional detection signals are introduced. The denoising algorithm is implemented in Matlab7.0 system simulation tools, and the denoising effects of these algorithms are compared.
