摘要：
In order to improve the precision of attitude estimation system, paper presents a signal extraction method of MEMS Gyroscope called VSCS-LMS algorithm based on FPGA. The design is established with the S-shaped function of sigmoid to reduce the sensitivity to noise of LMS algorithm. And its FPGA-based system structure is synthesized and simulated on Virtex II FPGA by reusing the single-order filter unit to complement the multi-order accumulation. The signal extraction simulation of MEMS gyroscope shows that it is reliable, high precision and high degree of real-time.
