In this chapter, we first give a brief overview about the development of cognitive radio networks (CRNs), from traditional CRNs to the recent development of wireless energy harvesting for CRNs. Then, we discuss how to integrate ambient backscatter communication techniques to radio-frequency (RF)-powered CRNs, and present two fundamental models for this integration. After that, we discuss recent advanced models of RF-powered CRNs with ambient backscatter communication with more details about system design, communication protocols, and performance optimization problems. Finally, some open issues for the development of RF-powered backscatter CRNs are presented.
