本文提出了一种新的方法来实现一个莱斯信道在BAN空中（OTA）测试使用的衰落仿真器与动态幻影。为了使所提出的装置有效，衰落仿真器必须具有表示室内实际传播环境的适当K因子。此外，莱斯信道的建议衰落仿真器在BAN的情况下的实现。之后，提出了一种用于衰落仿真器的校准方法，以调整体上Rice信道的实际K因子。通过分析摆臂运动引起的瞬时K因子的变化，验证了该标定方法的有效性。最后，利用该仿真器对一个摆臂动态体模进行了人体连续步行运动的仿真实验。结果表明，所开发的衰落仿真器能够在考虑人体步行运动动态特性的情况下，模拟真实的Rice信道传播环境，实现BAN-OTA测试。
This paper presents a new methodology for realizing a Rice channel in BAN Over-The-Air (OTA) testing using a fading emulator with a dynamic phantom. For the proposed apparatus to be effective, the fading emulator must be provided with an appropriate K-factor that represents the actual propagation environment indoors. Further, an implementation of the Rice channel to the proposed fading emulator in a BAN situation is presented. Thereafter, a calibration method for the fading emulator to adjust the actual K-factor of the on-body Rice channel is advanced. This calibration method is validated by analyzing the variations in the instantaneous K-factor attributed to the arm-swinging motion. Finally, an experiment is conducted for a continuous human walking motion with the fading emulator using an arm-swinging dynamic phantom. The results show that the developed fading emulator allows BAN-OTA testing to replicate the actual Rice channel propagation environment with the consideration of the dynamic characteristics of human walking motion.
