分析化学信号在多尺度空间的滤噪

De-noising of analytical chemistry signal in multi-scale space

从多分辨率分析出发,结合离散正交小波变换(DWT)的理论,通过对各尺度下未抽取前的小波系数进行非线性滤波处理,达到在保护信号边缘的同时,有效实现白噪声及脉冲噪声的滤除。实验数据仿真结果研究也证明了该方法的可行性。

Based on the multi-resolution analysis and the discrete orthogonal wavelet transform theory, a de-noising method was proposed to separate the wh ite and impulse noise and protect the edges of original signal. The method was used in simulation data with satisfactory results.
