| Abstract: | The technique of interference rejection for based on estimation,and working principle of the filter as well as LMS algorithm are introduced in this paper.According to the shortage of LMS,a new algorithm which improved the performance of LMS is presented,and is applied it to system simulation model.The simulating result shows that the suppression filter performs well in rejecting narrow band interference,and the new algorithm could improve the ability for anti-jamming system efficiency. |
