Wavelet filtering method in signal processing of fiber optic gyro
Hui Chen · Ha'erbin gongye daxue xuebao · 2004
Based on the definition of zero bias and zero drift in the fiber optic gyro (FOG),several de-noising algorithms on wavelet analysis are analyzed and the signal of FOG is processed. According to the results using several different basic wavelets, a method fitting engineering practice is proposed and in the meantime the result of the method is compared with the result of adaptive filtering.
