在本文中，一些离体通道，这是容易受到阴影所造成的人体进行了研究。特别是，最近提出的阴影κ-μ衰落模型拟合从现场试验中获得的数据在2.45 GHz的低多径条件下进行。结果表明，该模型提供了一个显着改善适合离体信道受到阴影相比，其他衰落模型，如对数正态分布，Nakagami-m和水稻通常适用于模型衰落在身体为中心的通信信道。
In this paper, a number of off-body channels which are susceptible to shadowing caused by the human body are investigated. In particular, the recently proposed shadowed κ-μ fading model is fitted to data obtained from field trials performed in low multipath conditions at 2.45 GHz. It is shown that this model provides a significantly improved fit to off-body channels which are subject to shadowing when compared to other fading models such as lognormal, Nakagami-m and Rice which are commonly applied to model fading in body centric communications channels.
