Abstract :
In this paper, the theory of wavelet packet analysis and the algorithms of wavelet packet decomposition and reconstruction are introduced. Then, the method of the application of wavelet packet analysis in the de-nosing of a MEMS vibrating ring gyro is given. At last, the effectiveness of this method is verified by an experiment.
