Abstract: Fast-ICA method is a popular good algorithm nowadays.Tt proposes a new independent component analysis algorithm which uses fourth-order cumulant as the optimized criterion,and improves Newton iteration method by analyzing batch processing fixed-point fast-ICA method.The validity and performance of the proposed algorithm are verified by extensive computer simulations.

Key words: blind signal separation； fourth-order cumulant； fast-ICA；
