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。
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.
