在无线通信的基础研究领域之一是现实的模型，可以有效地和准确地描述无线传播信道的发展。大多数提出的模型忽略了信号扩展的三维特征或使用计算复杂度过高的技术。在本文中，我们开发了一个简单的3-D几何散射模型的上行链路的宏小区移动的环境，提供了统计的到达角（AoA）的多径分量。该模型扩展了基于二维几何的单跳宏单元（GBSBM）模型。推导了方位角和仰角平面上多径到达角统计量的显式封闭表达式。结果分析表明，我们的建议相比，在文献中发表的2-D和3-D的优势。与实验数据的比较证实了其有效性。有趣的结论，有效的评估移动的通信系统已经得出。此外，应用该模型的移动的位置估计已开发和评估。
One of the fundamental research areas in wireless communications is the development of realistic models that can efficiently and accurately describe the wireless propagation channel. Most of the proposed models disregard the three dimensional character of the signal spread or use techniques with excessive computational complexity. In this paper, we develop a simple 3-D geometric scattering model for the uplink of a macrocell mobile environment that provides the statistics of Angle-of-Arrival (AoA) of the multipath components. The model extends the 2-D geometrical-based single bounce macrocell (GBSBM) model. Explicit closed-form expressions are derived for the statistics of the AoA of the multipaths in the azimuth and elevation planes. Analysis of the results exhibits the advantages of our proposal compared to 2-D and 3-D ones published in the literature. Comparisons with experimental data confirm its validity. Interesting conclusions for the effective evaluation of mobile communication systems have been derived. Moreover, an application of the model to mobile location estimation has been developed and evaluated.
