This book is the basic book for C/CPP Programmers.

An electrocardiogram (ECG) records the electrical activity of the heart. The heart produces tiny electrical impulses which spread through the heart muscle to make the heart contract. These impulses can be detected by the ECG machine. Electronic fetal ECG monitoring is a technique of obtaining important information about the condition of the fetus during pregnancy, by measuring the electrical signals generated by the fetal heart as measured multi-channel electrodes placed on the mother’s body surface. Fetal ECG (FECG) monitoring enables accurate measurement of fetal cardiac performance including transient or permanent abnormalities of rhythm. During labor and delivery, the heartbeat of the baby is monitored in order to make sure that enough blood flow and oxygen are getting through to the unborn fetus.

A dynamic estimation of channel is necessary before the transmission of the signals since the wireless channel is time–varying..we use MMSE method for channel estimation. The MMSE method calculates the following, MMSE channel estimator is designed to minimize the estimation MSE. The MMSE estimate the channel responses.
