Abstract

The development of fifth-generation (5G) systems is associated with the use of higher frequency bands and spatial multiplexing. A practical implementation of this multiplexing method is based on antenna arrays that allow the use of new technologies like active phased array antenna (APAA) or massive APAA. However, most of channel modeling methods available in a literature do not consider the selectivity of the transmitting and receiving antennas. In such cases, we can assume that the modeling is carried out for isotropic or omnidirectional antennas. In this paper, the angular dispersion modeling method for a 5G wireless link with directional antennas is shown what constitutes its novelty. The authors describe a multi-ellipsoid propagation model, which is the basis for simulation studies. Based on assumptions from real measurements for 38 GHz-39 GHz frequency range, an assessment of the influence of antenna directions and beamwidths on power angular spectrum and angle spreads in the azimuth and elevation planes is presented. The obtained simulation results show the importance of considering the three-dimensional modeling antenna patterns in the planning of 5G wireless lines.

带有定向天线的5G无线链路角色散建模

第五代(5G)系统的发展与更高频段和空间多路复用的使用有关。这种复用方法的实际实现基于天线阵列，该天线阵列允许使用新技术，如有源相控阵天线(APAA)或大规模APAA。然而，文献中大多数可用的信道建模方法都没有考虑发射和接收天线的选择性。在这种情况下，我们可以假设对各向同性或全向天线进行建模。本文阐述了定向天线5G无线链路的角色散建模方法的新颖性。建立了多椭球体传播模型，为仿真研究奠定了基础。基于38ghz ~ 39ghz频率范围的实际测量假设，评估了天线方向和波束宽度对功率角谱和角扩展在方位面和仰角面的影响。仿真结果表明，考虑天线方向图三维建模在5G无线线路规划中的重要性。
