Modeling of wireless based sensors data acquisitions systems used for esophagus monitoring
چکیده انگلیسی

This paper reports a new model for a wireless microsensor data acquisition system that can be used in diagnosing abnormalities in the esophagus. The proposed system incorporates pressure sensors for measuring the strength and pattern of muscle contractions that occur in the esophagus. Real data recorded by a manometry device, that detects pressure changes using developed sensors within a sealed cavity, is employed to assess the performance of the proposed system. Three different pulse coding modulation (PCM) and successive approximation register (SAR) analog to digital conversion algorithms are used for the channel coding. The created models were simulated and tested using SIMULINK® software. A behavioral model for FSK transceiver suitable for short-range applications has been developed. The transceiver system performance was tested under different conditions and the output simulation results were presented. The obtained output results from the different models are discussed.
