Performance of NOMA with Massive MIMO for 5G

This paper studies the performance of Non-Orthogonal Multiple Access (NOMA), for both conventional and cooperative NOMA, associated to Single Carrier with Frequency Domain Equalization (SC-FDE) block transmission technique, and to massive Multiple-Input Multiple-Output (MIMO). 5G makes use of millimeter wave communications (mm-Wave) and massive MIMO (m-MIMO). Moreover, NOMA is a potential solution, to be incorporated in future releases of 5G, to increase the capacity required to support extremely high number of Internet of Things (IoT). It is shown that combining NOMA with SC-FDE and mMIMO only suffers a moderate degradation, while a capacity gain is achieved due to the sharing of the spectrum.
