Blind source separation for underwater signals using onlytwo frequency bins

JIANG Wei-dong~(1,2), GAO Ming-sheng~(1), LU Ji-ren~(1)(1. Radio Engineering Department, Southeast University,Nanjing 210096,China)(2. Institute of Information & Electrics,Naval University of Engineering,Wuhan 430033,China)  
Underwater signals received by sonar are convolution mixtures. A new blind signal separation method using only two frequency bins is employed to separate the underwater signals. Amplitude and permutation indeterminacy can be eliminated and the validity of this method is confirmed by simulation experiments. In addition, the separation performance under different SNR is discussed.
