Abstract
Non-orthogonal multiple access (NOMA) has been achieving remarkable support in the surroundings of next generation communication system. The key advantages of this particular scheme includes high data rates, higher spectral and energy efficiency compared to its various orthogonal schemes. The upcoming next generation (5G) wireless networks requires high data rate as well as higher spectral and energy efficiency with very fast development of Internet of Things (IoT). In this paper, power domain based non-orthogonal multiple access (NOMA) scheme we adopted, which have been compared with already existing orthogonal scheme that is orthogonal frequency division multiple access (OFDMA) scheme. The simulation results show that the proposed NOMA scheme achieves much more data rate with higher spectral and energy efficiency as compared with existing technique.
