本文通过数值模拟和统计分析，研究了混响室中人体姿势对无线体域网（WBAN）测量的影响。在小型混响室中，采用旋转搅拌器和行走人体姿态模型。计算了观测点处的电场幅值，分析了电场幅值的分布。通过三因素方差分析，发现人的姿势对电场分布的影响比搅拌器的影响大。此外，还发现，当在室内用人体模型进行测量时，观察点的影响变大。在其他条件下进行模拟和分析，将结果与测量结果进行比较，有待进一步研究。
In this paper, the effect of human postures in a wireless body area network (WBAN) measurements in a reverberation chamber is investigated by numerical simulations and statistical analyses. A rotating stirrer and a walking human posture model are assumed in a small size reverberation chamber. Electric field amplitudes at observation points are calculated and the distributions of them are analyzed. As a result of the three-way analysis of variance, it is found that the human posture has a comparative effect on the electric field distribution than that of the stirrer. Also, it is found out that the effect of the observation points becomes large when conducting the measurement with a human model inside the chamber. To perform simulations and analyses with other conditions, to compare the results with measurements are left for further studies.
