Key result
Short-time Fourier transform (STFT) enhances maternal abdominal ECG recordings for efficient separation and extraction of the foetal electrocardiogram.
Why the study?
Obtaining a clean non-invasive foetal ECG is challenging due to low signal quality, which impedes morphological wave structure examination during pregnancy and labour.

Short-time Fourier transform with a Kaiser window can enhance maternal abdominal ECG recordings to improve the extraction and morphological analysis of fetal ECGs.
The objective of the project is to improve maternal abdomen recording for better prediction of foetal Electrocardiogram (FECG). One of the most difficult tasks in observing foetal well-being is obtaining a clean foetal Electrocardiogram (FECG) using non-invasive abdominal recordings. The foetal graph's low signal quality, on the other hand, makes morphological examination of its wave structure in clinical follow-up difficult. The signal contains precise information that can help doctors to monitor fetal health during pregnancy and labor. The abdominal signal is normalized and separated in the pre-processing stage for wave shape analysis in clinical follow-up. The Kaiser window is used for spectral analysis and segmenting the signal. The two-dimensional (2D) time-frequency representation is obtained by short-time Fourier transform (STFT). The STFT enhances the abdominal recordings of maternal Electrocardiogram (MECG) for efficient separation of foetal electrocardiogram (FECG) to monitor the foetus well-being.
