The design aim is to optimally allocate the secondary resources to improve the throughput of secondary users while maintaining a certain quality of service for primary users. The analytical results of optimal resource allocation are derived via optimization theory and are verified by the numerical results. The results demonstrate the secondary performance is significantly improved by limited feedback and is further improved by more feedback bits, more secondary receivers and more primary side information.SpringerBriefs in Electrical and Computer Engineering,2191-8112Electrical engineeringComputer communication systemsCommunications Engineering, Networkshttps://scigraph.springernature.com/ontologies/product-market-codes/T24035Computer Communication Networkshttps://scigraph.springernature.com/ontologies/product-market-codes/I13022Electrical engineering.Computer communication systems.Communications Engineering, Networks.Computer Communication Networks.621.384Wang Zheauthttp://id.loc.gov/vocabulary/relators/aut720647Zhang Weiauthttp://id.loc.gov/vocabulary/relators/autBOOK9910299687303321Opportunistic Spectrum Sharing in Cognitive Radio Networks2521952UNINA
