Abstract
This paper proposes a joint transmit antenna selection (TAS) and selection combining (SC)-assisted multi-hop decode-and-forward (DF) scheme employing power-domain non-orthogonal multiple access (PD-NOMA). In the proposed protocol, a source transmits its data to a destination via a preestablished multi-hop route. TAS/SC is applied at each hop to enhance transmission reliability. Meanwhile, PD-NOMA is utilized to simultaneously transmit the source data and the data of an additional node that is not part of the source-destination route. We evaluate the end-to-end (e2e) outage probability (OPe2e) and system throughput (TP-e2e) of the proposed scheme through both analytical derivations and simulations over Rayleigh fading channels. The results show that the proposed scheme achieves the same diversity gain as the conventional TAS/SC-assisted multi-hop DF scheme without PD-NOMA. In addition, at high transmit signal-to-noise ratio (SNR) regions, the proposed scheme provides a significantly higher multiplexing gain.
This paper enhances the proposed system cell-edge user performance and derives analytical frameworks for outage probability, throughput, and ergodic capacity of PR, SR, respectively and determines the optimal power allocation scheme to enhance the performance of PR/SR signals.
Simulation results demonstrate that the proposed multi-RIS-assisted DF relaying cooperative scheme significantly outperforms both the DF-only and multi-RIS-only schemes, and system performance improves as the number of RIS reflecting elements increases, in line with the law of diminishing marginal returns.
