摘要

通过在办公室内的实际测量，提出了一种UWB体上天线及其传播信道模型，并对其系统性能进行了评估。为此，首先通过测量两个紧凑体上天线的电磁耦合数据来研究体上信道传递函数(CTF)，提取其路径损耗(PL)和功率延迟曲线(PDP)参数。其次，在推导的AP信道模型的基础上，研究了两种UWB体上通信系统的性能。最后，对仿真结果进行了总结。需要指出的是，现有的超宽带对体通信能力还有待进一步提高。

Performance of WBAN UWB system based on the measured on-body channel model

A UWB on-body antenna and propagation (AP) channel model is presented through its realistic measurements in an office room, along with its system performance evaluated. To this end, on-body channel transfer function (CTF) is firstly investigated by measuring two compact on-body antennas electromagnetic (EM) coupled data, with which both its parameters of pathloss (PL) and power delay profile (PDP) are extracted. Secondly, two kinds of UWB on-body communication system performance are studied, based on the derived AP channel model. Finally, some conclusions are given concerning the simulated results. It should be pointed out that the existing UWB on-body communication abilities should be greatly improved.
