摘要
本文首先对噪声污染的信号作乘性转换为加性的同态变换,实现信噪分离,然后应用线性滤波方法进行处理,最后作同态变换的逆变换,达到去噪和压缩的效果。
This article according to the noise while the essence, causes it for the additive Gauss noise using the isomorphic transformation, then by suits the processing additive noise the Lee filter to carry on chirp,finally makes the isomorphic transformation the corresponding inverse transformation, this algorithm effectively reduced the noise.
