本文研究了无线体域网络(WBANs)中的特定主题无线电信道。该仿真工具基于一种并行的时域有限差分法(FDTD)，非常适合于模拟WBAN中复杂的、非均匀目标(包括人体)的电波传播。我们的研究发现，当接收到的信号主要包含人体周围爬行波的贡献时，WBAN中的无线电信道特性是特定于对象的。
This paper presents a study of subject-specific radio channels in wireless body area networks (WBANs). The simulation tool is based on a parallel finite-difference timedomain method (FDTD) and is well suited to model radio propagations around complex, inhomogeneous objects including human bodies in WBAN. It is found from our study that radio channel characteristics in WBAN are subject specific when the received signal mainly contains the contribution of creeping waves around the human body.
