Abstract

Unlike the conventional Non-Orthogonal Multiple Access (NOMA) can agree much more users by the no orthogonal available source allocation the maximizing energy efficiency (EE) and spectral efficiency (SE) in Massive multi-input–multi-output systems (MIMO) are the most critical to get higher spectrum efficiency and battery-saving technology to diverse use high data traffic in next-fifth generation (5G). We first must understand the idea of this system of NOMA to use in the radio access in the future for 5G technology. Whereas is necessary to achieving SE and EE without immolation of the quality of service (QoS) on mobile devices. The Performance of ES and EE can be achieved when the all antennas available are used. Then we furnish with the basis for both downlink and uplink, also explain how the network can use the best capacity. Also we research of effect incomplete the receivers in doing on the NOMA networks. At last, our research of SE on the networks that use with the relations to EE. We explain the networks with NOMA better than MA expression, in the total capacity, the maximizing EE and SE. The study aim is discussing how can obtain a high SE and maximizing EE with the reduce power consumed and to achieve the better data rate of the increase the number of the antennas when NOMA in the case of downlink when used massive MIMO system.
