仿真方法在研究体内通信(IBC)中起着重要作用。由于传递函数和相应参数的问题，目前只实现了电流耦合IBC沿臂的仿真。本文介绍了一种对不同信号传输路径的电流耦合IBC进行数学仿真的方法。首先，在考虑IBC器件内阻的基础上，推导了电流耦合IBC的新传递函数。其次，详细讨论了传递函数中相应参数的确定。最后，对不同信号传输路径上的电流耦合IBC进行了测量和仿真。研究表明，在100 kHz~5 MHz的频率范围内，数学仿真结果与测量结果吻合较好，表明该方法在电流耦合IBC的理论分析和应用中具有明显的优势。
The simulation method plays an important role in the investigation of the intrabody communication (IBC). Due to the problems of the transfer function and the corresponding parameters, only the simulation of the galvanic coupling IBC along the arm has been achieved at present. In this paper, a method for the mathematical simulation of the galvanic coupling IBC with different signal transmission paths has been introduced. First, a new transfer function of the galvanic coupling IBC was derived with the consideration of the internal resistances of the IBC devices. Second, the determination of the corresponding parameters used in the transfer function was discussed in detail. Finally, both the measurements and the simulations of the galvanic coupling IBC along the different signal transmission paths were carried out. Our investigation shows that the mathematical simulation results coincide with the measurement results over the frequency range from 100 kHz to 5 MHz, which indicates that the proposed method offers the significant advantages in the theoretical analysis and the application of the galvanic coupling IBC.
