| Abstract: | This paper presents a new hybrid noise cancellation scheme employing Adaptive Beamforming and Fast Independent Component Analysis. The method can restrain noise and enhances speech with stability and fast convergence. Furthermore the influence upon this algorithm when the number of units or input signals of adaptive beamforming varies is studied, which is significant to practical application . |
