摘要

以巡检机器人为代表的终端设备在变电站中应用广泛，第五代移动通信（5G）技术发展迅速，未来5G可移动终端在变电站的应用将会越来越多。通信系统的性能与无线信道息息相关，因此研究变电站中可移动终端的5G通信信道特性至关重要。文章针对变电站三维（3D）散射环境下5G可移动终端的通信信道的特性问题，基于多输入多输出技术，提出采用几何分析法建立3D信道模型，并推导出了信道的时间自相关函数、空间互相关函数。基于5G频段，仿真并分析了无线信道的自相关和互相关特性；研究了不同大小的莱斯因子对无线信道特性的影响。上述仿真结果表明了5G终端在变电站的可用性，拓宽了变电站场景下可移动终端运用5G通信技术的研究。

Abstract

Terminal equipment represented by inspection robots is widely used in substations. In the future

5th-Generation (5G) mobile terminals will be more and more used in substations with the fast development of 5G technology. The performance of the communication system is closely related to the wireless channel. Therefore

it is very important to study the 5G communication channel characteristics of the mobile terminal in the substation. Aiming at the characteristics of the communication channel of 5G mobile terminals in the Three-Dimension (3D) scattering environment of substations

based on the multiple input multiple output technology

the article proposes to use geometric analysis to establish a 3D channel model

and derive the time autocorrelation function and spatial cross correlation function of the channel. Based on the 5G frequency band

the autocorrelation and cross-correlation characteristics of the wireless channel are simulated and analyzed. The influence of the Rice factor of different sizes on the wireless channel characteristics is also studied. The above simulation results show the availability of 5G terminals in substations

and broaden the research on mobile terminals using 5G communication technology in substation scenarios.
