极化方式是电波传播的重要特性,也是在信道传播特性中的关键要素。文章基于入射及反弹射线/镜像方法(SBR/Image)研究了室内无线电波传播特性,考虑了两次(甚至任意次)反射的极化特性,建立起三维的室内视距模型。通过仿真计算,首先证明了研究极化特性的必要性;然后将仿真结果和已知文献结果对比,两个结果一致性良好,同时验证了本文的正确性。
Polarization is an important feature of radio wave propagation and is also a key element in channel propagation characteristics. In this paper, the propagation characteristics of indoor radio waves are studied based on incident and bounce radiation / mirroring method (SBR / Image). The polarization characteristics of two (or even any) reflections are considered and a three-dimensional indoor line-of-sight model is established. Through the simulation calculation, firstly, the necessity of studying polarization characteristics is proved. Then, the simulation results are compared with the known literature results, the consistency of the two results is good, and the correctness of the paper is verified.
