PDMA技术在车联网通信中的应用研究
|
摘要
5G时代的到来无疑给物联网、工业互联网等产业的发展带来了重大变革,尤其是给车联网的发展创造了一个良好的机遇。本着解决目前车联网中通信中吞吐量与时延问题的目的,结合5G核心技术图样分割多址原理与性能,设计基于PDMA的5G车联网系统结构,并与传统正交传输方式进行数据传输速率的比较,最后进行仿真证明PDMA技术在车联网的通信应用中能够明显提高其吞吐量。
The arrival of the 5 G era has undoubtedly brought about major changes in the development of the Internet of Things, Industrial Internet and other industries, especially creating a good opportunity for the development of the Internet of Vehicles.In order to solve the problem of throughput and delay in communication in the current Internet of Vehicles, this paper combines 5 G core technology pattern to divide the principle and performance of multiple access, design PDMA-based 5 G car networking system structure, and carry out data with traditional orthogonal transmission mode. The comparison of transmission rates, and finally the simulation proves that PDMA technology can significantly improve its throughput in the communication application of the Internet of Vehicles.
