论文摘要
卫星和地面通信系统的集成在第五代移动通信系统（5G）中起着至关重要的作用，用于无处不在的覆盖范围，可靠的服务和灵活的网络。此外，毫米波（mmwave）与大带宽的通信是5G智能铁路运输的关键推动力。在本文中，在典型的高速铁路（HSR）环境中，将22.6 GHz处的卫星 - 地球通道进行了特征。铁路方案的三维模型被重建并导入到云射线追踪（Cloudrt）仿真平台中。基于广泛的射线追踪模拟，表征了具有两种天气条件的陆地hsr系统和卫星 - 地物系统的通道，并评估了它们之间的干扰。本文的结果可以帮助卫星 - 事务通信系统的设计和评估，从而实现未来的智能铁路运输。
The integration of satellite and terrestrial communication systems plays a vital role in the fifth-generation mobile communication system (5G) for the ubiquitous coverage, reliable service and flexible networking. Moreover, the millimeter wave (mmWave) communication with large bandwidth is a key enabler for 5G intelligent rail transportation. In this paper, the satellite-terrestrial channel at 22.6 GHz is characterized for a typical high-speed railway (HSR) environment. The three-dimensional model of the railway scenario is reconstructed and imported into the Cloud Ray-Tracing (CloudRT) simulation platform. Based on extensive ray-tracing simulations, the channel for the terrestrial HSR system and the satellite-terrestrial system with two weather conditions are characterized, and the interference between them are evaluated. The results of this paper can help for the design and evaluation for the satellite-terrestrial communication system enabling future intelligent rail transportation.
