Performance Analysis of Multi-Source Two-way NOMA-AF Relaying Networks

In this paper, we propose multiple sources (MS) for two-way non-orthogonal-multiple-access (NOMA) cooperative amplify-and-forward (AF) networks. We propose a system with MS, two relays and two users, where MS transmit a superposed message to two users via a AF relays on the first hop. We study the performance of two-way MS-NOMA-AF in terms of sum-rate. We present how MS effects of the performance of the suggested two-way NOMA system. We examine the simulation results to confirm that our suggested mathematical analysis is accurate.
