NOMA in Cooperative Underlay Cognitive Radio Networks Under Imperfect SIC
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 provides higher spectrum efficiency when detecting the presence of the PN. Hence, spectrum utilization of the traditional sch...
