摘要
应用MATLAB小波工具箱中的一维小波包分析函数,采用默认阈值、调节后的阈值两种方法对含噪声的信号进行处理,并以一可见吸收光谱降噪为例,说明该方法在信号降噪中有效可行.
One-dimentional wavelet packet analytic function in MATLAB wavelet toobox is applied to eliminate noises in signal by acuiescent and variational theshold.In this paper,eliminate noises in visile spectroscope as an example,estimate the results of eliminating noises by two ways.The results are satisfactory.So,it is proved that wavelet packet analysis is doable in signal denoise.
