The rapidly increasing number of wireless systems is exacerbating the already significant challenge of limited frequency spectrum bandwidth in modern wireless systems. To address this scarcity of spectrum, secondary systems can adopt an opportunistic approach by accessing temporarily unused licensed bands of primary systems. This approach, known as cognitive radio technology, allows secondary systems to modify their transmitting parameters. so to minimize interference with primary users. The problem of spectral crowding can be addressed by utilizing cognitive radio technology, which involves opportunistically utilizing frequency bands that are not heavily occupied by licensed users. This approach provides a promising solution to the challenge of limited frequency spectrum bandwidth in modern wireless systems. With the development of prototypes and the implementation of these approaches on testbeds, researcher scan the effectiveness of cognitive radio approaches and ensure their successful deployment in the real world. The application of cognitive radio technology has attracted significant research interest and has the potential to introduce new approaches to the usage of available spectrum, thereby improving the efficiency of wireless systems.
