| 摘 要： | 信噪分离是小波包应用于信号分析的一个重要方面。本文在基于MATLAB的基础上,采用小波包对含高斯白噪声信号进行分解,通过不同的量化阈值对小波包系数进行处理、重构得出小波包消噪后的信号。计算机仿真结果表明,用不同量化阈值的小波包可对含高斯白声信号进行消噪重构。

| Abstract: | Signal and eliminating noise were important using wavelet package, this paper, introduced the signal using Mallab with wavelet package, and processed the wavelet package coefficient recur to these hold value, and finally got the wanted signal with instruction, the computer simulation results showed that selecting the different threshold wavelet packages can got reconstruction signal about eliminating noise. |
