An overview of cognitive radio in 5G wireless communications
S. Sasipriya, R. Vigneshram · 2016
5G and Cognitive Radio (CR) are the two emerging technologies to meet the heavy mobile data traffic of future wireless networks. The new era of communication will be dominated by 5G in future. As the future mobile broadband will be largely driven by ultra high definition video and as the things around us will be always connected, 5G aims to provide higher capacity and a network speed of 10Gbps. 5G equipment will also be available at lower cost, lower battery consumption and lower latency than 4G equipment. 5G platform can empower the growth of many industries ranging from entertainment, agriculture, IT and manufacturing industries. The need for more capacity will demand more spectrums resulting in integration of CR in 5G networks. The focus of CR is to enable much more efficient use of the spectrum though it adapts itself to provide the optimum communications channel. This paper is based on the review of cognitive radio in 5G wireless communication system.
