| 摘 要： | 在LabVIEW软件平台下,应用UWT(非降采样小波变换)算法设计一新型处理软件,该软件集合了db5、coif5、sym5等三种不同正交小波的信号分解、阈值去噪和信号重构算法,并使用该软件成功地还原了一带噪语音信号,得出在强噪声背景下,该小波变换算法具有良好的保留语音原信号特性且降噪效果优越的结论。

| Abstract: | In the LabVIEW software platform,using UWT (undecimated wavelet transform)algorithm to design a new type of processing software,the software combines db5,coif5,sym5 three different orthogonal wavelet signal decomposition,thresholding denoise and signal reconstruction algorithm and use the software successfully revert a noisy speech signal and conclude that the wavelet transform algorithm has good retention characteristics of the original signal in strong background noise and the voice is superior noise reduction. |
