A novel ICA algorithm for two sources

In the independent component analysis (ICA) algorithms, almost all algebraic methods and some adaptive methods can be expressed as "whitening\´\´ and "rotating". However, the whitening is just suitable for the simplest ICA model, it may be necessary to develop new algorithm frameworks, which do not need whitening preprocessing. In this paper, a novel algorithm for 2 sources is proposed, which is last, stable, and does not require whitening. Simulation results are presented, showing good performance of the new algorithm.
