摘要
Cognitive radio networks (CRN) is IEEE 802.22 standards, also known as 5-G wireless technology. CRN carries primary users (PU) or licensed users and secondary users (CR) or un-licensed users. In this paper, we have presented an overview of CRN, further we discuss CRN functions. There are various sensing techniques which we classify and discuss, and further analyze the issues related to CRN. Finally, we conclude that each sensing technique has its own advantages and dis-advantages.
