摘　　要：5G是一个高速率、超带宽、低时延和超高密度连接的移动通信网络体系。作为面向5G关键技术的非正交多址接入技术(NOMA),第一次将功率域由单用户独占改为由多用户共享,使无线接入总量提高了50%。原理的简单性使其在5G应用中具有一定的竞争优势。首先介绍了NOMA的基本原理,而后分析了NOMA的关键技术SIC接收机,分析了NOMA技术应用中的相关困难,最后总结了5G应用带给人们的相关体验和NOMA实现存在的问题。5G is a mobile communication network system with high speed, super bandwidth, low time delay and super high density link. The NOMA, orienting 5G key technology, changes firstly the occupation of power area from single user to multi user. The total wireless access amount increases 50%. The simplification of the NOMA principle, gives the competition advantages in 5G ap- plication. It presents the basic principles of NOMA, then analyzes SIC receiver, which is the key technologies of NOMA, ana- lyzes the related difficulty in NOMA application. Finally it concludes the related experience on 5G application and the problems on NOMA.
