Select of Wavelet Basis in Gyro Signal Processing
Luyuan Liu · Journal of Chinese Inertial Technology · 2002
A new math model was built. Gyro signals were decomposed into different scales by four kinds wavelets to discard wavelet coefficient that created by noise and complete noise eliminating. Different results were compared through simulated experiment and bior1.5 wavelet show better performance. The importance of wavelet symmetry is proved in gyro signal processing.
