| Abstract: | This paper propose a novel alterative step LMS auto-adapted filter algorithm based on mean squared-error estimation.Compare to the traditional LMS algorithm,it attains a faster convergence speed and less stability maladjustment.Applying this algorithm to simulate the auto-adapted noise elimination system,simulated results were given out.The results were consistent with the theoretic analysis,which shows the advantage of the novel algorithm. |
