摘要
讨论了一种基于小波变换的信号去噪方法,从3种不同的去噪方法比较中看出小波变换在信号去噪中的优越性,数值实验及实际运用都证明了该方法的有效性.
The signal denoise method based on wavelet transform is discussed in the paper.Among three different method comparisons,denoise is the most effective.The feasibility of the method is demonstrated by several numeric experiment models and field examples.
