摘　　要：针对传统小波变换在信号消噪中计算的不足,设计了一种改进的小波消噪算法。该算法保留了小波分析处理时变信号的优势所在,但较传统的消噪应用,算法相对简单,易于实现。利用实际数据对该消噪算法进行了数据验证,并与传统小波消噪算法等对比算法进行了效果对比。验证结果表明,所提出的新算法效果较好,具有一定实用性。In view of the deficiency of traditional wavelet denosing method, an improved wavelet denosing algorithm was designed. The new algorithm has the same advantage as traditional wavelet denosing algorithm in analyzing time-varying signals. However, it is simpler and can easily be carried out than traditional method. The new denoising algorithm was tested with real data, and compared with the traditional wavelet denosing algorithm. The result shows that the new algorithm is effective and applicable.
