构建运动状态下的人体通信信道传播模型，对人体通信收发器进一步降低功耗、延长工作时间、缩小体积、降低设计复杂度都具有重要意义。而现有的研究都未能精确地揭示人体通信动态信道传播机理。本项目拟在前期人体通信传播信道建模及应用研究的基础上，通过分析人体物理几何结构及组织的电磁学特性，结合人体的运动特征，建立非均匀介质人体模型；基于上述模型，研究非均匀介质人体环境中多种信号源的激励响应特性，并采用时域有限差分算法解析基于非均匀介质的人体通信传播特性；进一步研究对高分辨率连续运动帧时间序列的非均匀介质仿真分析方法，结合实验统计分析，最终建立非均匀介质人体环境中的人体通信动态信道传播模型。本研究不仅对人体通信动态信道进行了全面深入的数值建模，还为穿戴式计算应用中的无线通信动态信道分析提供了重要的理论基础和学术价值。

The modeling of the dynamic propagation channel for human body communication (HBC) will give more advantageous in transceiver design, such as reducing the energy consumption, extending the working hours, minimizing the volume and simplifying the complexity of the design. However, the recent researches have not precisely clarify the dynamic HBC propagation mechanism. Based on our previous working on the characteristics of HBC propagation channel, in this proposal, we will firstly analyze the physical geometrical structure of human body and the electromagnetic characteristic of tissues, and considering the body movement, so as to model the inhomogeneous medium model for human body; secondly, we will investigate the response of different signal sources in aforementioned inhomogeneous medium model, and then will adopt FDTD to study the HBC propagation characteristics; finally, we will investigate the simulate method for the time series of continuous movement frame based on the inhomogeneous medium model, by adopting the experimental verification, we will establish the dynamic propagation channel for HBC based on inhomogeneous human medium model. This research will not only comprehensive model the dynamic HBC channel, but only provide important theoretical guidance and academic value for analyzing the dynamic channel propagation in wearable communications .
