| 摘 要： | 本文在分析经典的软阈值和硬阈值降噪方法的基础上,提出了一种改进方案,同时克服了软阈值和硬阈值方法的缺点。通过Matlab实验,结果表明本文提出的改进方案明显比单纯的软阈值和硬阈值方法降噪效果好。

| Abstract: | Based on the analysis of two traditional wavelet de-noising methods, which are based on soft-threshold and hard-threshold strategy respectively, an improved method is proposed here. It overcomes the shortcomings of the traditional nonlinear threshold strategy. Simulations results based on Matlab have revealed that the improved method does better than traditional threshold strategy in de-noising. |
