| Abstract: | According to the wireless communication characters of gastrointestinal inspecting instrument,the wireless channel simulation model between the transmitter of capsule and external receiver was set up.Based on the model,the effects on communication channel caused by signal to noise and the impairment of human tissues were analyzed.Taking frame error rate as an evaluation standard of communication performance,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. |
