A Sensor Signal Process System Based On LMS Algorithm

Adaptive filtering technology is the important component on modem digital filtering technology,which can automatically adjust filter parameters on the filtering process, and then achieve optimal filtering effect. Adaptive filter algorithm is the important algorithm on adaptive filtering technologies, which is design good or bad have a direct impact on the filtering effect with filter. However, the minimum mean square algorithm(LMS) with its high stability, simple calculation, and achieve easily, which is widely used in the system engineering, missile technology, aerospace technology, digital communication technology,remote sensing technology and other high-end areas.This paper mainly discussed influence in LMS algorithm.Combined with other new LMS algorithm, 3 new algorithms is proposed and put in comparison.As experiment and stimulation turn out that the algorithm based on the function of cosine is more stable and efficient. Genetic algorithm is applied for improvement of modified algorithms Then,MATLAB and DSP Builder is combined to stimulate the experiment of newly proposed algorithm...
