对一组混有高斯噪声的正弦型号进行独立分量的滤波处理并观察其效果，从而发现了独立分量分析的方法对于信号的处理是很有好处的，方法简单得到的效果也很直观(Mixed with a group of sinusoidal Gaussian noise model of independent component filtering and observe the effect, so that an independent component analysis approach for signal processing is very good, simple to get the effect is very intuitive)

说明：  小波阈值去噪的基本思想是先设置一个临界阈值λ，若小波系数小于λ，认为该系数主要由噪声引起，去除这部分系数;若小波系数大于λ，则认为此系数主要是由信号引起，保留这部分系数，然后对处理后的小波系数进行小波逆变换得到去噪后的信号。(The basic idea of wavelet threshold denoising is to set a threshold value of lambda first. If the wavelet coefficient is less than lambda, it is considered that the coefficient is mainly caused by noise and this part of the coefficient is removed. If the wavelet coefficient is larger than lambda, it is considered that the coefficient is mainly caused by signal, and this part of the coefficient is retained. Then the denoised signal is obtained by inverse wavelet transform of the processed wavelet coefficient.)
