摘要
车联网是未来智慧交通的重要组成部分,是目前移动通信领域的研究热点。作为我国重点推进的技术手段,C-V2X已经得到了产业界和学术界的重视。无线信道是通信系统研究设计的基础,因此有必要对C-V2X信道特性展开研究。结合实际测试对C-V2X信道特性进行了分析,梳理了传统信道建模方法,针对传统方法的不足介绍了基于机器学习的信道建模方法,对其应用进行了阐述。
The Internet of Vehicles is an important part of the future intelligent transportation and a research hotspot in mobile communication fields.As a key technical means to promote in China,C-V2X has attracted the attention of industry and academia.Wireless channel is the basis of communication system research and design,and it is necessary to study the channel characteristics of C-V2X.The characteristics of C-V2X channel are analyzed in combination with actual test,and the traditional channel modeling methods are combed.To deal with the shortcoming of the traditional methods,a machine learning-based channel modeling method is introduced,and its applications are provided.
