As an application of adaptive signal processing to biomedical engineering, fetal ECG extraction is well-known and has been studied continuously in force from 1980's. However, this technology has not been put into fetal diagnosis practice yet due to low extraction accuracy. If established and put into daily diagnosis, it will become a high technology that contributes greatly to fulfilling the public demands for security and safety of birth in low birth-rate age we live in. In this project, linear and nonlinear adaptive noise cancellers are proposed that have both multiple primary and reference channels. Applications to real fetal ECG data reveal that the new systems present much better extraction accuracy than the conventional system indicates. Thus, this project has achieved a significant progress toward general use of the technology.

作为自适应信号处理在生物医学工程中的一个应用，胎儿心电信号的提取一直是人们关注的热点。然而，由于提取准确率低，该技术尚未应用于胎儿诊断实践。如果建立并投入日常诊断，它将成为一项高技术，大大有助于满足我们生活在低生育率时代的公众对生育安全和保障的需求。在这个项目中，线性和非线性自适应噪声消除器提出了具有多个主通道和参考通道。对真实的胎儿心电数据的应用表明，新系统比传统系统具有更好的提取精度。因此，该项目在该技术的普遍使用方面取得了重大进展。
