Interference Aware Design of NOMA for Large-Scale 5G Networks

As there is rapid increase in the field of mobile service technologies, the numbers of users are increasing drastically with respect to the access of mobile services. 3rd generation partnership projects LTE (3GPP) technology is the most absorbed technology for the users. It has dominant role with respect to increased data rate, video service, and other mobile services. The orthogonal multiple access unable to provide the high data rate, within scarce bandwidth, so the new technique is introduced namely, Non-orthogonal Multiple Access(NOMA). NOMA is introduced as a non orthogonal multiple access which is a key component of 5G cellular networks. Many of the NOMA schemes proposed so far are unable to manage intercell interference efficiently, which is one of the performance limiting parameter in 5G networks. In this respect proposed measures negative impact of intercell interference on NOMA performance for resolving the same, interference aware design is discussed. In real time we neither neglect the interference nor we make it zero, hence minimization of interference for better system performance is proposed, hence to mitigate the interference Zero Forcing(ZF)equalization technique is used.
