Reconfigurable Intelligent Surface Enhanced Cognitive Radio Networks

22 May 2020 Jinglian He Kaiqiang Yu Yong Zhou Yuanming Shi

The cognitive radio (CR) network is a promising network architecture that meets the requirement of enhancing scarce radio spectrum utilization. Meanwhile, reconfigurable intelligent surfaces (RIS) is a promising solution to enhance the energy and spectrum efficiency of wireless networks by properly altering the signal propagation via tuning a large number of passive reflecting units...
