代码描述

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
