In 5G-based cognitive radio, the primary user signal is more active thanks to the broad frequency band. The normal cooperative spectrum sensing only senses one characteristic of PU using one kind of detector. Cognitive radio (CR) has arisen as a promising technique to the spectrum scarcity problem faced by all current just as recently proposed wireless administrations. In cognitive radio network (CRN) spectrum sensing assumes the main part and is considered as a basic part of CR. The individual CR node may not give valid detecting results due to shadowing and secret terminal problems of wirele...
