Blind signal procession of Silicon Micromachined Gyroscope

Silicon micromachined gyroscope (SMG) is a new sensor technique used for rolling object moving control. One of the difficulty is how to get position parameters from gyroscope signal that is a multiplicave blind signal. This paper analysis the signal property and provide several methods to get the position parameters. The results show the new method do well. Otherwise as the signal from SMG contains struggle noise, we adopt some methods to cancel the noise. Results also show the methods very efficient.
