| 摘 要： | 人体心电信号在采集过程中掺杂着各种噪声信号。因而提出利用一种非线性的消噪方法，根据心电信号与噪声奇异点在小波变换下不同性质进行滤波。给出了具体的算法和试验结果。理论分析和实验表明，这种方法在改善信噪比同时又能保持相当主的时间分辨率，而且特别适合时变信号和突变信号的消噪。

| Abstract: | The ECG when acquired is often combined with various noises. In this paper, we propose a nonlinear method to eliminate the noise. It can be filtered according to the different properties of the signal and the noise. The algorithm and experimental results were given. The theoretical analysis and experimental results shows that this method not only can improve the S/N but also can keep higher time resolution and particularly be suited to the time-varying signal and mutation signal. |
