摘要
文中针对研制自适应胎儿心电图仪和提取胎儿心电(FECG)信号的特点,根据自适应噪声抵消(ANC)原理,研究与实现了几种自适应噪声抵消软件算法,滤除母亲心电(MECG)和其它干扰,无创无损提取胎儿心电信号。并通过实例,对这几种算法进行比较、分析讨论。
In view of the developmenl of an adaptive Fetal Electrocardiogragh（FECG） and the characteristics of distilling the FECG, this paper researched and implemented several adaptive noise canceling algorithms, which are based on the principle of ANC. They can filter the disturbance of MECG and other signal, so that it can extract FECG signal with non invasion. Comparison, analysis and discussion among these algorithms are made with real examples.
