Abstract: Multiple access is a key procedure which is used from 1G to 4G communication. Different multiple access techniques in different generations create difference in data rate, connectivity, outage performance etc. 5G is the recent technology in which a new multiple access technique must be used to increase the outage performance, massive connectivity and data rate for next generation. This paper gives clear idea about the Non-Orthogonal Multiple Access (NOMA) technique and different challenges to overcome in NOMA and also a brief description of different power allocation techniques is mentioned. The data rate performance of OFDMA and NOMA are evaluated and shown how spectral efficiency can be increased using NOMA.
