Extraction and Analysis of Fetal ECG Lead
Abstract: The design of the main application of independent component analysis (Independent Component Analysis, ICA) is applied to the analysis and simulation using the Matlab simulation software. The paper firstly introduces related knowledge of human ECG signal, expounds the theoretical basis and principle of independent component analysis method, and the principle of simulation. Then using the ICA algorithm combined with Matlab software simulation, to separate the maternal body 8 signal, the simulation results proved that the ICA algorithm can be successfully isolated from fetal ECG signal is very pure.
