摘要：

In this paper, cooperative relay networks with non-orthogonal multiple access (CRN-NOMA) is analyzed, with a view to designing a near-optimal power allocation (PA) strategy. Like other next generation wireless technologies, spatially multiplexed transmissions are achieved by relay nodes which enable decode-and-forward (DF) relaying of a new superposition code after reception from the source. The proposed PA scheme carries the caveat that it cannot be classically validated because it is only one kind of approximation conjecture. Results indicate that the sum-rate (SR) performance of the proposed scheme is nearly optimal at a higher signal-to-noise ratio (SNR) with negligible performance loss.
