中文说明：通过第二代提升小波分解对一维信号去噪，而且针对传统软硬阈值去噪的缺陷，构造了一种新的阈值函数，结果表明，去噪后的信号信噪比大大提高
English Description：
By the second generation of lifting wavelet decomposition of a one-dimensional signal de-noising, and traditional hard and soft thresholding defects, construct a new threshold function, the results show that the signal to noise ratio is greatly improved after de-noising
