A comparison study of two de-noising methods based on the wavelet analysis and the matching pursuit approaches was performed. Using the Matlab software,a set of typical noise signals in engineering applications were used to de-noise and to be compared.

• 对基于小波和匹配跟踪的两种降噪方法进行了比较研究,利用Matlab软件对几种典型的噪声信号使用以上两种方法进行了降噪处理,并结合处理结果对这两种降噪方法进行了分析比较。
