Application of Wavelet Analysis in Gyro Signal Filtering
Wan Yan-hui, Qing Yong-yuan · Piezoelectrics and Acoustooptics · 2005
The method to filter through wavelet analysis is presented, and the gyro random drift model is set up.Gyro signals were decomposed into different scales by four kinds wavelets to discard wavelet coefficients by soft-thresholding.Then the signal is filtered after wavelet re-configed.The result confirms that this method is effective.
