Abstract
Telemetry is the process for sensing and measuring of information at some remote location and then transmitting that information to desire location. It is very useful for medical monitoring too. The electrical activity of heart is measured in the form of electrocardiogram (ECG). The monitoring of fetus ECG (FECG) is important to monitor the baby inside mom abdomen. The observation during labour and delivery is done by monitoring fetus heart rate (FHR). It is also useful in biomedical telemetry and telemedicine. The abdominal electrocardiogram (AECG) consist of FECG as well as maternal electrocardiogram (MECG). The amplitude of FECG is very less in compare to MECG. So its difficult so separate. In this paper we use orthogonal frequency division multiplexing (OFDM) for transmission from remote area with high signal to noise ratio (SNR). Wavelet transforms (WT) and artificial intelligence systems is used to de-noise composite signal and to obtain FCEG from AECG. All coding is done in MATLAB software. The artificial neural network and fuzzy interference system (ANFIS) is used to obtain exact FECG at desired location.
