Embracing non-orthogonal multiple access in future wireless networks
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.
