摘要
本文系统分析了基于小波变换的门限值去噪方法,研究了小波变换门限值选择的准则及其算法。通过计算机仿真,比较了各种准则的性能,验证了基于小波变换门限值去噪方法的滤波效果。仿真结果表明,基于小波变换门限值的去噪方法可以有效地去除宽带噪声。
The door method to paper. As well as the rule and de-noise on the basis of wavelet transform is emphatically analyzed in this arithmetic of wavelet transform door value choice. Through computer emulation, the performance of various rules is compared and the filter effect on the basis of wavelet transform door method to broadband noise de-noise is also validated. According to emulation result, this kind of method can restrain effectively by using this de-noising technique.
