这封信提出了一个定量的方法来调查特定主题的身体沟通渠道。为了这个目的，在5.8 GHz的传播进行了研究，考虑到50个现实的数字幻影，统计产生的一组20磁共振（MR）扫描。视线（LoS）和非视线（NLoS）通信链路都已考虑在内。提出了反映身体尺寸（特别是身高和腰围）和路径损耗变化之间的相关性的数学表达式。结果表明，路径损耗变化和体型参数之间可以外推线性拟合。在内部并行时域有限差分（PFDTD）数值方法已被应用于进行全波模拟的50数字幻影。
This letter presents a quantitative approach to the investigation of subject-specific on-body communication channels. To this aim, propagation at 5.8 GHz has been studied considering 50 realistic digital phantoms, statistically generated from a set of 20 magnetic resonance (MR) scans. Both line-of-sight (LoS) and nonline-of-sight (NLoS) communication links have been taken into account. Mathematical expressions are proposed reflecting the correlation between body dimensions (specifically height and waist) and path-loss variation. Results show that linear fitting can be extrapolated between path-loss variations and body shape parameters. In-house parallel finite-difference time-domain (PFDTD) numerical method has been applied to carry out full-wave simulations on the 50 digital phantoms.
