Application of the Wavelet Transformation in the MEMS Gyroscope De-Noise
Xunsheng Ji · Chuangan jishu xuebao · 2006
The wavelet theory was introduced. The residual signal from the gyroscope was decomposed by the different scale biorthogonal stationary wavelet base. The result showed that the Bior1.1 wavelet had the better performance. The coefficients of the decomposing filter and the rebuilding filter were also very simple. It proved that the wavelet transformation was feasible in the de-noising of the gyroscope drifting signal.
