| 摘 要： | 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。结果表明两种方法各有所长,分别适合不同类型信号的降噪处理。另外,还做了一些关于数据处理的工程应用方面的工作。

| Abstract: | 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.The comparison results suggested that the two de-noising techniques under consideration can be adopted in processing different types of signals and each having its own advantages.And also,some useful conclusions were drawn,which will benefit the signal processing engineering. |
