5G通讯的技术现状及面临的挑战

The Current Status and Challenges of 5G Communication Technology

在当今社会中通讯技术是必不可少的一项重要科学技术。在这个高速发展的时代,5G通讯技术的应用更加广泛,但同时也面临着许多挑战与机遇。本文首先梳理了不同时代的通信方法,并对通信科学的一些瓶颈进行分析。然后论述了5G通信的关键技术,包括MIMO,稀疏多址,全双工技术等。本文主要对5G所面对的难题进行了详细研究,并重点分析了频段、频谱、系统容量、成本和终端设备等多方面的问题。为以后学者的进一步研究提供了参考和基准。

Communication technology is an important and indispensable science and technology in today's society.And 5G communication technology is at the forefront.In this era of rapid development,5G communication technology is more widely used,but it also faces many challenges and opportunities.Firstly,this paper combs the communication methods of different times,and analyses some bottlenecks of communication science.Then the key technologies of 5G communication are discussed,including MIMO,sparse multiple access,full duplex technology and so on.Unlike previous studies,this paper mainly studies the problems faced by 5G in detail,and focuses on the analysis of frequency band,spectrum,system capacity,cost and terminal equipment.It provides a reference and benchmark for the further research of scholars in the future.Furthermore,this paper looks forward to the revolutionary changes that 5G technology will bring to society,especially mobile Internet and Internet of Things,after breaking through the relevant bottlenecks.
