摘要：
Independent component analysis (ICA) has attracted much attention in the field of signal processing. A novel method of speech signal enhancement by using modified FastICA algorithm is presented in this paper. The principle and merits of the modified Fast,ICA algorithm are discussed in detail. Simulations and experimental results show that the performance of the new method based on the modified FastICA algorithm is satisfactory to broad band noise and other noisy signals from the same channel.
