On Secondary Throughput Maximization and Eavesdropping Protection in RIS-Aided Underlay Green Cognitive Radio Networks
In this work, a reconfigurable intelligent surface (RIS)-aided energy harvesting (EH) scheme on cognitive radio network (CRN), operating in an underlay mode, is considered in presence of an eavesdropper. Both primary user (PU) and secondary user (SU) networks, each one consisting of one transmitter-receiver pair, share...
