【Abstract】 Based on the specialty of multi-resolution analysis of wavelet and the mathematical model of fiber optic gyro (FOG), a de-noising algorithm using threshold value is presented. By comparing the different results using several basic wavelets, the feasibility of this de-noising algorithm is verified.
