摘要
介绍了小波理论知识,分析了阈值去噪法的特点。并针对小波阈值萎缩去噪方法的阈值函数选取问题进行了详细讨论,然后对常用的五种阈值选择规则进行了仿真试验。
The paper introduces the wavelet theory and analyses the character of the removing noise by the valve.According to the valve function of the removing noise,it has discussed the selected questions in detail and simulated the five common rules in choosing the valve.
