On Non-Orthogonal Multiple Access (NOMA) in 5G Systems
The Journal of Korean Institute of Communications and Information Sciences, 2015 The non-orthogonal multiple access (NOMA) is one of the fledging paradigms which next generation radio access technologies are sprouting toward. The NOMA with superposition coding (SC) in the transmitter and successive interference cancellation (SIC) at the receiver comes with many desirable features and benefits over orthogonal multiple access (OMA ...
