考虑到在移动的通信中朝向以用户为中心的概念的趋势，体域网在无线个人和体域网社区内受到越来越多的关注。在本文中，实验研究，以获得合适的超宽带（UWB）身体为中心的无线通信的无线电传播模型。研究了以人体为中心的UWB无线信道的性能，考虑了几个身体上的链路，包括不同的身体姿势。潜在的多频带正交频分复用超宽带系统的系统级建模已进行和系统性能的测量，使用误码率（BER）和信噪比。所进行的系统分析表明，对于78%的静态情况，以及75%和61%的稳定和不稳定的发射机位置，在指定的体上无线电链路的伪动态运动场景中（分别），BER等于或小于0.1%。这证明了所提出的UWB身体为中心的无线电系统的应用前景。基于这些结果，给出了明确的建议，最佳的身体上的位置，导致最佳的系统性能。
Given the trend towards a user-centric concept in mobile communications, body area networks have received increasing attention within the wireless personal and body area networks community. In this paper, an experimental investigation is presented to derive suitable radio propagation models for ultra wideband (UWB) body-centric wireless communications. The performance of the body-centric UWB radio channel is investigated by considering several on-body links, including different body postures. System-level modeling of potential multiband orthogonal frequency-division multiplexed UWB system has been conducted and system performance is measured using bit error rate (BER) and signal-to-noise ratio. The conducted system analysis demonstrated that for 78% in the static case and 75% and 61% for stable and unstable transmitter locations in the pseudodynamic in-motion scenarios (respectively) of the specified on-body radio links, the BER is equal to or less than 0.1%. This demonstrates promising applications of the proposed UWB body-centric radio system. Based on these results, clear recommendations are given for best on-body locations leading to optimal system performance.
