摘要

水泥表面的散射特性对城市环境下第五代(5G)移动通信的时间和角度色散具有重要影响。通过室外环境实验，获得了不同入射角下水泥粗糙墙面的28 GHz散射分布。测量结果表明，散射信号的分布不符合常规射线追踪中使用的朗伯分布。与兰伯特分布相比，在镜面方向附近散射系数最大，而在其他方向散射系数小于镜面分布。散射系数可以用来模拟信号在城市环境中的传播，以提高系统的可靠性。

Study on the Scattering Coefficients of the Cement Surface at 28GHz

The scattering properties of the cement surface play an important role in determining time and angle dispersion of the fifth-generation (5G) mobile communication in urban environment. The 28 GHz scattering distribution of the rough cement wall surface (RCWS) were acquired by the outdoor environment experiment at different incidence angles in this paper. The measurements reveal that the dlstributions of the scattering signals don't conform to the Lambert distribution used in the conventional ray tracing. The scattering coefficient reaches up to the maximum near the specular direction compared with the Lambert distribution, Moreover the other direction is less than the specular one. The scattering coefficients can be applied to simulate the signal propagation in urban environments to improve the reliability of the system.
