| Abstract: | With the rapid growth of wireless technologies,the spectrum scarcity has become a serious problem.The cognitive radio technology can effectively solve the spectrum tense actuality.In this paper,we will first introduce the concept of cognitive radio,and then the ways to detect spectrum holes.In order to improve detection probability and reduce equipment complex and computation complex,to combine UWB with the cognitive radio,we present collaborative sensing method based on energy detection and user's cooperation(EDAUC).Simulation and analysis results show that the method can effectively improve detecting spectrum holes probability. |
| Keywords: | Cognitive radio spectrum sensing energy detection collaborative sensing |
