Abstract

In order to eliminate the speech signal fading induced by noise, this paper proposes a new variable leaky LMS algorithm on the basis of the adaptive filter in combination with the advantages of the leakage LMS algorithm and the variable step size LMS algorithm, and analyzes its principle. After the new algorithm is used to simulate speech with noise, the result shows that the proposed algorithm has a good ability to suppress Gaussian noise and excellent tracking performance, proving the correctness of the algorithm and the feasibility of simulation.
