利用高阶统计量进行心肺音信号的盲分离

Blind Source Separation of Heart Signal and Lung Signal Based on High-order Statistics

根据心肺音信号采集的特点,提出利用利用高阶统计量对心肺音信号进行盲分离。这样可以有效地去除高斯有色噪声,并对肺音信号采集时的一个重要干扰源——心音信号进行分离。

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.
