Performing Strategic Spectrum Sensing Study for the Cognitive Radio Networks

In order to address the spectrum scarcity issues that affect today's wireless services, the concept of cognitive radio has been proposed. A licensed spectrum is made available to smart and adaptable secondary users through this framework. Because of cognitive radio technology, these unlicensed secondary users can take advantage of any spectrum utilization opportunity by dynamically adjusting their broadcast characteristics. In this study, we explore the defining aspects and primary capabilities of cognitive radio focused technology. As well as Spectrum sensing has been considered a key enabling technology for cognitive radio based wireless networks of the future. In this paper, we evaluate and contrast a variety of technologies in terms of their sensing sensitivity, the complexity of implementation, and computational demands. Several problems with spectrum sensing have been studied, and several opinions have been presented.
