Abstract |
|
The radio frequency spectrum is very limited natural resource and recent spectrum occupancy measurements and studies have shown that pre-allocated spectrum bands are rarely occupied full time by primary users. Cognitive radio is an emerging wireless technology that allows efficient spectrum utilization by allowing secondary users to access the unoccupied frequency bands, called spectrum holes. With the capability to sense the operating environment, learn and adapt in real time environment, cognitive radio technology is seen as the most promising technology for future wireless communication networks. In this paper, we have explored the concept of cognitive radio and other aspects related to spectrum sensing. In addition to this, various challenges of spectrum sensing are also discussed. |
