| Research Abstract |
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.
