In conventional cognitive radio (CR), the users in secondary network (SN) can only access
the idle spectrum when users in primary network (PN) are absent. This novel strategy …

Non-orthogonal multiple access (NOMA) and cognitive radio (CR) are envisioned as
promising solutions to achieve high spectral efficiency for future wireless networks. This …

This correspondence paper considers a dual-hop underlay cognitive radio nonorthogonal
