在体内通信系统的发展中，最具挑战性的目标是防止其他电子设备产生的噪声。本文基于静电场理论，推导了体内通信信道中环境噪声电场（即辐射噪声）的等效电路表达式。此外，通过基于矩量法的静电分析给出了数值算例，结果与基于时域有限差分法的全波分析和实测结果相吻合。因此，本文提出的电路模型可以很好地表达环境噪声电场的贡献。
In the development of intrabody communication systems, the most challenging goal is to protect against noise due to other electronic devices. In this paper, the equivalent-circuit expression of environmental noise electric fields (the so-called radiated noise) in intrabody communication channels are derived based on the theory of electrostatic fields. In addition, numerical examples are shown by means of electrostatic analysis based on the method of moments, and the results agree with those by full-wave analysis based on the finite-difference time-domain method and those by measurements. Therefore, it is concluded that the proposed circuit model can properly express the contribution of environmental noise electric fields.
