Abstract :
This paper introduces the basic theory of ICA and the FastICA algorithm. In order to increase the algorithm convergence rate and reduce the running time, the paper which is based on FastICA algorithm proposes an improved independent component analysis algorithm with Newton´s iteration- the “Newton Type” iteration algorithm with third-order convergence. The simulation results of the image signal separation show that the improved algorithm have the same separate effect as conventional FastICA algorithm and can reduce the times of iterations.
