Abstract
The aim of this paper is to design and implement a medical telemetry system. The device shall be critical in the application of Foetal and Maternal care. With wireless systems, patients can move freely around the hospital while their physiological parameters like Uterine activity, Foetal heart rate and Foetal ECG/Maternal ECG are measured. The captured data is then transmitted wirelessly to a receiver unit using frequency ranges within Wireless Medical Telemetry Service(WMTS) band. The spread spectrum transmission is used in the WMTS telemetry systems. It is a technique in which pseudo noise code is modulated with the data signal for spreading. The spreaded signals are used for suppressing the interference during the propagation. The interference occurs when number of users share a common channel bandwidth. The spreaded signal is then transmitted to the receiver, where the spread spectrum detector despreads the data signal. The data signal thus retrieved is used for monitoring and investigations.
