  • A new blind signal separation method, where only one frequency bin is used, is presented to separate the underwater signals. Using this method, the indeterminacy in amplitude and permutation can be eliminated, and the validity of this method is confirmed by simulation experiment. Compared with the separation algorithm based on two frequency bins, this new method has better separation performance and less operation time. Therefore, the separation algorithm based on single frequency bin is more suitable for real-time signal separation.
