摘要 介绍了小波变换的基本理论,研究了信号和白噪声在小波变换下的不同特性,在此基础上提出了一种新的基于小波变换的白噪声消除方法.仿真结果证明,这种方法具有很好的去噪声效果. In this paper,after briefly introducing wavelet transform,the different property between signals and white noises under the wavelet transform is analysed.A new method for white noise reduction based on wavelet transform is presented.Finally,experimental result is given to demonstrate the effectiveness of the method.
