Abstract
The cognitive radio network provides high bandwidth for mobile users to reconstruct wireless architecture and dynamic spectrum access technology. The spectrum allocation is the key to cognitive radio spectrum resources for the relative scarcity of radio spectrum resources. The spectrum allocation algorithm must have faster convergence speed to adapt to the time-varying characteristics of cognitive radio networks. In this paper, a spectrum sensing method is proposed based on high-order anti-jamming mechanism for cognitive radio spectrum allocation. Firstly, the combination of cognitive anti-jamming spectrum sensing, channel estimation, learning comprehension, time-hopping frequency hopping, spectrum access control and other technologies can improve the anti-jamming ability. Secondly, cognitive radio can effectively improve the utilization of spectrum resources according to the different benefits of different users on different channels, achieve the best matching between cognitive users and channels and flexible spectrum allocation. Finally, the effectiveness of the proposed algorithm is verified by simulation experiments.
