随着越来越多的无线设备在医疗、军事和个人通信应用中可穿戴，身体上通信信道受到越来越多的关注。本文对人体运动引起的在体通道的动态特性进行了实验研究。统计分析，包括水平交叉率，衰落持续时间，和衰落间隔进行。在此基础上，提出了一种考虑通道停留时间的三态Fritchman模型来描述人体通道的动态特性。信道被分类为不稳定的良好状态、恒定的良好状态和不良状态。Fritchman模型的参数是根据测量数据估计的。
On-body communication channels are of increasing interest as more and more wireless devices are wearable in medical, military, and personal communication applications. This paper presents an experimental investigation of the dynamic feature of on-body channel due to the movement of human body. Statistical analyses, including level crossing rate, fading duration, and fading interval were conducted. Based on the analyses, a three-state Fritchman model that considers the channel dwelling time is proposed to describe the dynamic characteristic of on-body channel. The channel is classified as unstable good state, constant good state, and bad state. The parameters of the Fritchman model are estimated from the measured data.
