Abstract

This correspondence paper considers a dual-hop underlay cognitive radio nonorthogonal multiple access (NOMA) network. The end-to-end outage probability (OP) is evaluated as the performance metric for secondary NOMA users. Furthermore, the OP results of NOMA is compared with conventional orthogonal multiple access to show the supremacy of the former. Representative numerical and simulation results corroborate the effectiveness of the proposed scheme and presented analysis.
