Indeterminacies in amplitude and permutation are the two main cumbersome aspects for blind signal separation in frequency domain. Based on the fact that there is a good amplitude correlation between neighbour bins of a speech signal, we presented a new blind source separation method that can eliminate the permutation indeterminacy. Since there is no complicated mathematic derivation in this method, it is relatively simple in theory. Furthermore, the outcome of multiply simulation experiments confirmed its validity in blind source separation of speech signals. In addition, this method is robust and time saving.
