Simulation of a biomedical wireless acquisition system for recording the GI motor activity

The work presented in this paper introduces different simulation models for a wireless system used for diagnosing the peristalsis motor activity of the gastrointestinal tract. Real data recorded by a manometer device, that detects pressure changes 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 SIMULINKreg 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
