摘要
目前,4G技术是现时代人们通信的主要方式,随着科技的发展,各个国家都越加重视对通信技术的研究,5G时代必将到来。这篇文章首先对5G通信技术作了简述,接着阐述了5G通信技术的发展趋势,表明不管是从利用率处理效率还是安全性上来讲,它将都会是下一个年代通信技术的标准,也是人们对这一技术的期望。最后从无线传输技术角度出发,从大规模天线技术、全双工技术以及基于滤波器组的多载波技术三个方面分析了5G通信的关键技术。
At present, 4 G technology is the main way of communication in modern times. With the development of science and technology, every country pays more attention to the research of communication technology, and the 5 G era is bound to come. Firstly, this paper gives a brief introduction to 5 G communication technology, and then expounds the development trend of 5 G communication technology. It shows that it will be the standard of communication technology in the next generation, whether in terms of utilization efficiency or security, and it is also the expectation of people for this technology. Finally, from the perspective of wireless transmission technology, the key technologies of5 G communication are analyzed from three aspects: large-scale antenna technology, full duplex technology and multi-carrier technology based on filter banks.
