This paper considers cognitive radio (CR) inspired non-orthogonal multiple-access (NOMA). Such NOMA users with performance improvement can be achieved as deploying relay selection schemes. In this investigation, NOMA and CR scheme are considered as promising techniques to introduce new model of CR-N...
