Abstract

The non-orthogonal multiple access (NOMA) multiple access technique, due to its non-orthogonality and providing access to users together, which have the same frequency and time resource, made it a front runner to meet the need of high traffic requirements networks. In this paper, a downlink, NOMA, and cooperative NOMA (CNOMA) are compared with varying different parameters: source transmit power, user transmit power, and power allocation for achievable sum rates. Simulation results show that the CNOMA achieves a higher sum rate as compared to NOMA for all the parameters.
