体域网中的高效收发器设计需要深入了解传播信道，在这种情况下，传播信道涉及人体。已经进行了几项研究来表征身体表面上的RF传播并确定适当模型的参数。然而，直到最近的测量实验期间，才考虑到现有医疗植入物对体表传播的可能影响。在那里，发现主动脉植入物可能对植入位置附近的可穿戴节点之间的超宽带（UWB）传播具有影响。在本文中，我们使用3D沉浸式可视化环境来研究和观察主动脉植入物对体表传播的影响。具体来说，我们专注于UWB脉冲响应的节点位于周围的上半身之间的信道。在测量和模拟中获得的脉冲响应（对于有和没有植入物的情况）的差异表明此类医疗植入物可能对体表RF传播产生影响。
Efficient transceiver design in body area networks requires in-depth understanding of the propagation channel which in this case involves the human body. Several studies have been done to characterize RF propagation on the body surface and determine the parameters of an appropriate model. However, the possible effect of an already existing medical implant on body surface propagation has not been considered until during a recent measurement experiment. There it was discovered that an aortic implant may have an impact on Ultra Wide-Band (UWB) propagation between wearable nodes that are in the vicinity of the implant location. In this paper, we use a 3D immersive visualization environment to study and observe the impact of an aortic implant on body surface propagation. Specifically, we focus on the UWB impulse response of the channel between nodes located around the upper body. The difference in the obtained impulse responses (for scenarios with and without the implant) both in measurement and simulation points to the possible impact that such medical implants could have on body surface RF propagation.
