摘要:

本文首先采用RLS自适应算法对心电信号进行实时建模。经过约20个心电周期,本算法使可以基本完成自身的调整。利用多尺度理论,将小波分析和Kalman滤波结合起来,在对信号预测的同时定位心电信号的R峰。对于心电信号中因伪迹造成的误判,可通过在小波检测方法中设置相应的检测策略克服。实验表明,该算法提高了抗噪声性能。

Abstract:

In this paper, we first build a real-time electrocardiograph signal model using the RLS self-adapting algorithm. After about 20 periods, this algorith m can implement its proper adjustment. According to the multi-scale theory and by integrating wavelet analysis with the Kalman filtering, we can predict  signals as well as locate the R mount for electrocardiograph signals. The misjudgement which is produced by the false tracks in electrocardiograph sign als can be avoided through setting the corresponding detection policies using the wavelet detection method. The algorithm can enhance the noise resistan ce performance.
