1	NOMA and Its Applications: A Survey Thi Dep Ha Abstract - Non-orthogonal multiple access (NOMA) has been recognized as an emerging technology that can enhance spectral efficiency, throughput, data rate, and latency in future 5G wireless networks. Thus, NOMA has been considered by many researchers in the last decade. In this paper, we present an overview of NOMA technology and its application in cellular networks and unmanned aerial vehicles (UAVs). In addition, we also describe in detail the superposition coding (SC) and successive interference cancellation (SIC) mechanisms. Furthermore, the performance metrics of the NOMA based wireless networks, including outage probability, throughput, and energy efficiency, are analyzed. Finally, the challenges in NOMA network systems in terms of imperfect SIC and imperfect CSI are provided. Therefore, this survey provides the fundamentals of NOMA for findings of this latest technology.	Download
