| 摘 要： | 针对工业过程数据含有噪声干扰的特点,本文提出了基于小波包分解的阈值降噪方法进行数据的降噪处理。以化工过程数据为例,通过MATLAB仿真实验,对比了小波包降噪、小波降噪、中值滤波三种方法的降噪效果。结果表明:小波包降噪具有明显的优越性。

| Abstract: | Aimed at the feature of the industry process data contains noises,this paper proposed wavelet packet threshold de-noising method for noise reduction.Simulated test is made by MATLAB on chemical industry datum.The de-noising capabilities of three methods(wavelet packet threshold de-noising,wavelet threshold de-noising,medium filter) were compared and analysed.The results show that wavelet packet threshold de-noising method is superior to the other two kinds of methods. |
