双正交小波在陀螺信号去噪中的应用

The Gyro Signal Processing Through Biorthogonal Wavelet Transform

本文在用双正交小波对陀螺信号进行不同尺度分解的基础上,结合传统的信号分析方法,得出小波系数是由噪声产生的,从而提出合适的小波去噪方法。本方法在应用中得到较好的去噪效果。

In this paper, biorthogonal wavelet transform and other tradition Signal Processing methods are used to analysis Gyro signal. Because wavelet coefficients are generaled by noise, a reasonable de-noising method is presented.An effective filtering result is got by using this method.
