| 摘 要： | 从信号去噪的角度对小波变换作了分析,并且对用非线性小波从噪声中提取有用信号的算法作了对比研究,给出了几种方法的综合方法——变阈值消噪方法,以得到更好的消噪效果。应用对微弱检测信号的仿真试验验证了变阈值消噪算法的优越性。

| Abstract: | Viewed from signal de-noising, the wavelet analysis theory is introduced. The several algorithms of extracting useful signal from noise using the nonlinear wavelet are compared and the synthesis method, that is, vary threshold quantity de-noising method is provided to get the better effect. The simulation test using the weak signal detection demonstrated the superiority of the vary threshold quantity de-noising method. |
