Zhaoning Zhang · Infrared and Laser Engineering · 2006
The theory of the wavelet transform is introduced.The mathematical model of the MEMS Gyro is built.The theory of wavelet transform is used in the processing of the MEMS Gyro signals,and according to two states of the MEMS Gyro,filtering results using the Daubechies(Db) wavelets are analyzed,comparing to the filtering result using a two order IIRfilter.And the efficiency of MEMS Gyro signal denoising using Daubechies(Db) wavelets is proved.
