胃肠动力诊查仪的无线通信系统仿真

The Simulation on Wireless Communication System of Gastrointestinal Inspecting Instrument

根据胃肠动力诊查仪的无线通信特性,建立从胶囊发射器到体外数据接收存储器的无线通信信道的仿真模型.重点分析了信噪比和由于人体组织吸收所产生的损耗对通信性能的影响.把误帧率作为通信性能的评价标准,设计了动态编码协议,保证了系统通信的可靠性.仿真结果为胃肠动力诊查仪的无线通信系统的通信协议设计、信道编码设计等提供了参考依据.

According to the wireless communication characters of gastrointestinal inspecting instrument,the wireless channel simulation model between the transmitter of capsule and external Based on the model, the effects on communication channel caused by signal to noise a human tissues were analyzed. Taking frame error rate as an evaluation standard of receiver was set up. nd the impairment of communication pertormance, the dynamic coding protocol was designed which assures the reliability of communication. The simulation results provide an effective reference for the designs of wireless communication protocol, channel coding etc.
