[Blind source separation of heart signal and lung signal based on high-order statistics].
Based on the characteristics of heart sound and lung sound, we propose to use high-order statistics to achieve the blind source separation of these signals. In this way, we can abstract lung sound signal from heart sound signal clearly.
