Performance Examination of Relay Supported Cooperative NOMA Network

Non-Orthogonal Multiple Access (NOMA) is a communication methodology used in modern cellular networks that has higher spectral efficiency than the traditional schemes like TDMA, OFDMA, CDMA etc. by enabling more than one user can communicate simultaneously. Sometimes, direct transmission among the transmitter and receiver is not possible because the distance between them is greater than the transmitting range of the source. This decreases the network capacity and coverage. So, to overcome this problem this article proposes a relay supported network which can improve the network capacity by reducing the distance between the source and destination. Simulation results demonstrate that the proposed scheme has the highest achievable sum rate of the existing conventional scheme.
