中文摘要： 人体中心可穿戴无线通信由于在医疗护理检测、士兵定位识别等领域具有十分广阔的应用前景，是未来个人无线通信技术发展的必然趋势之一。但研究现状表明，其研究与发展的一个关键且具有基础性意义的障碍就是缺少适用于人体中心可穿戴无线通信系统的信道模型。为此，本项目提出探索电磁波与人体相互作用的物理机制，揭示可穿戴无线通信系统中的电磁波传播规律并建立相应信道模型。天线与人体强耦合，使得人体成为了天线组成部分，导致了人体表面、体内各节点间的电磁波传播具有强的近场耦合特征。项目将充分考虑这一特点，通过理论分析、数值模拟以及实验等手段，借鉴传统远场信道模型，建立反映强近场耦合特征、全面考虑节点位置及人体姿态等因素的人体表面－表面、表面－体内无线通信链路半确定性信道模型；针对各信道特点，研究能提高信道增益的天线设计新技术；探索人体表面无线节点的最佳分布，增强系统可靠性与效率，同时完成对可穿戴系统的最优性能设计。

英文摘要： Wearable wireless communications of human body, one of inevitable trends of the future development of personal wireless communications technologies, has very broad application prospects in the field of care testing, soldiers positioned recognition and so on. However, recent researches indicate that a key obstacle with fundamental significance of research and development is the lack of wearable wireless communication system in the center of the body channel model. To this end, the project is proposed to explore the physical mechanism of the interaction between electromagnetic waves and human reveals wearable electromagnetic wave propagation in wireless communication systems and to establish the corresponding channel model. Strong coupling, which is between antenna and human body, make the human body as a component of an antenna. Also, this leads to a strong near-field coupling characteristics of the body surface electromagnetic wave propagation between nodes of the body. The project will take full account of that characteristic, through theoretical analysis, numerical simulations and experiments, using traditional far field channel models for reference, the semi-deterministic channel model of surface-surface and surface-body wireless communication link, which indicates the characteristic of strong near-field coup
