| Abstract: | A novel approach about multistage adaptive algorithm for speech enhancement is proposed,based on broadband LCMV(Linearly Constrained Minimum Variance) theory and the ANC(Adaptive Noise Cancelation) theory.The signals are collected in the real acoustic environment.Then the algorithm is validated using the MATLAB simulation tools.The results show that the complexity of the new method is simple and efficient,and there is little distortion to speech signals.Moreover,it is marketable for the improvement of the S... |
