Abstract

Massive MIMO becomes a key technology for the fifth generation (5G) of mobile communications that will improve major performances such as higher data rates, more reliability, lower latency and more channel capacities. Along with the requirement of higher frequency bandwidth in 5G, the most referred frequency band is in the range of 26-28 GHz which has an extremely short wavelength. Thus it naturally causes the shortening of the signal distribution distance due to the large signal attenuation. Comparing with the 4G mobile communication, the overall performance of 5G could be inferior to 4G by higher frequency band but it can be compensated by using more number of antennas for massive MIMO integrating with more antenna gain for each antenna element. In this paper, the study of gain effect to improve the performance of 5G communications is presented. The key performances in terms of throughput and spectral efficiency are examined to be a useful guideline for further designing on 5G massive MIMO.

从4G向5G移动通信过渡的大规模MIMO增益补偿

大规模MIMO成为第五代(5G)移动通信的关键技术，将提高主要性能，如更高的数据速率、更高的可靠性、更低的延迟和更大的信道容量。随着5G对更高频率带宽的要求，被提及最多的频段在26- 28ghz范围内，该频段波长极短。这样，由于信号衰减大，自然造成信号分布距离的缩短。与4G移动通信相比，5G的整体性能可能会因更高的频带而不如4G，但可以通过使用更多天线数量进行大规模MIMO来弥补，每个天线单元的天线增益更高。本文研究了提高5G通信性能的增益效应。研究了吞吐量和频谱效率方面的关键性能，为进一步设计5G大规模MIMO提供了有用的指导。
