The explosive growth of wireless data services, especially more and more requirement for high-definition videos, demands higher capacity of future wireless communication systems to meet this trend. One efficient solution to this problem is to improve the spectral efficiency. The basic principles of large-scale antenna array system is analyzed, whose performance is verified by simulation. Key technologies on large-scale antenna array system, such as channel state information acquisition, antenna array design, codebook design, are also researched. The results show that large-scale antenna array system can greatly improve spectral efficiency and reduce system energy consumption.
