Impacts of relay and direct links at destinations in full-duplex non-orthogonal multiple access system

In this study, one of effective methods multiple access, namely non-orthogonal access (NOMA), is investigated. Such NOMA scheme can be worked with signal processing at downlink side. As such, the base station sends mixed signals two to destinations. A near user could a relay forward distant by leveraging benefits full-duplex mode which allows transmit and receive in same time. For simple analysis, two-user approach fixed power allocation factors are implemented. We also derive formulas outage probability users (near-user far-user) indicate fairness emphasize role as relay. This considered system adopts transmission Nakagami-m fading channel. further metric, throughput under impacts key parameters. The signal-to-noise ratio (SNR) make influences performance significantly observation indicated our simulation results. These results confirmed matching Monte-Carlo theoretical simulations.
