中文摘要：
生物无线传感器网络由于其需要植入人体内部，故热效应是其研究的一个热点。超宽带信号由于覆盖频率范围广，使其以往的研究仅仅停留在定性研究的阶段。本文首先提出一个适合于研究物理层技术对热效应影响的系统模型，然后，在此基础上利用加权平均的方法分析超宽带生物无线传感器网络的热效应，得出超宽带信号对人体热效应影响较弱的结论，并对进一步的研究工作提出了展望。
英文摘要：
The thermal effect was regarded as a topical point in the biosensor networks which was a kind of implanted wireless sensor networks. Because UWB signal covers a wide range of frequencies, previous study on it only stayed in qualitative research stage. This article proposed a simulation model that is suitable to study thermal effects in the physical layer, and then, the thermal effects of UWB signal was analyzed with the method of the weighted average. The result shows that UWB signals have weaker thermal effects.
