小波变换及其在信号消噪中的应用
Wavelet transform and its application in noise-removing
本文在分析傅里叶变换的基础上，总结其在噪声消除方面的不足，并由此引出小波变换在信号消噪处理中的作用。最后应用MATLAB给出仿真的结果，证明了小波变换在消除突变信号过程中的优越性。
On the base of analysis about Fourier transform, this paper concludes the deficiency of Fourier transform in noise-removing, then elicit the effect of wavelet transform in noise-removing. At the end of this paper, a MATLAB simulation result is given, and proves the superiority of wavelet transform in saltation signal removing.
