Embracing non-orthogonal multiple access in future wireless networks

本文就新兴通信技术——非正交多址接入(non-orthogonal multiple access,NOMA)——对未来无线网络的影响进行了全面综述。具体地,介绍了NOMA原理对下一代多址接入技术设计的影响。讨论了NOMA在其他先进通信技术上的应用,包括无线缓存、多入多出技术、毫米波通信以及协同中继。阐述了NOMA对蜂窝网络之外通信系统的影响,例如数字电视、卫星通信、车联网及可见光通信。最后,讨论并总结了NOMA的主要研究挑战及未来发展方向。

This paper provides a comprehensive survey of the impact of the emerging communication technique, non-orthogonal multiple access （NOMA）, on future wireless networks. Particularly, how the NOMA principle affects the design of the generation multiple access techniques is introduced first. Then the applications of NOMA to other advanced communication techniques, such as wireless caching, multiple-input multiple-output techniques, millimeter-wave communications, and cooperative relaying, are discussed. The impact of NOMA on communication systems beyond cellular networks is also illustrated, through the examples of digital TV, satellite communications, vehicular networks, and visible light communications. Finally, the study is concluded with a discussion of important research challenges and promising future directions in NOMA.
