摘要
The increasing number of devices and high data speed requirements are putting a challenge. To address these problems 5G is implemented. The Orthogonal Multiple Access (OMA) schemes are not sufficient for the implementation of the 5G. One of the promising Multiple Access Technique is Non Orthogonal Multiple Access Technique (NOMA). In NOMA the entire users use the same resource so there will be interference from the others users. In order to transmit data and recover it correctly, this research work utilizes the Successive Interference Cancellation (SIC), which will increase the receiver complexity but has the benefit of high connectivity and spectral efficiency. This paper has analysed different variants in NOMA and presented the most prominent works and compared NOMA with OMA. The challenges for implementing NOMA commercially have also been addressed elaborately.
