Summary: A novel fast blind source separation algorithm is presented to solve the problem of phase ambiguity in blind source separation of complex-valued digital communication signal. The algorithm extends the FastICA algorithm which is only applied to the real-valued signal to the complex-valued digital communication signal. The algorithm also eliminates the phase ambiguity of the communication complex-valued signals having the independent in-phase and quadrature components. The algorithm doesn't consider the selection of step size and has fast convergence speed. Furthermore, the algorithm has stable separation performance just like FastICA algorithm. Simulation results show that the algorithm can separate not only the signals with the different carrier frequencies, but also with the same carrier frequencies; not only with the different modulation model, but also with the same modulation model.
