An Improved Channel Selection Method of Cognitive Radio
Yingxiao Wu · Journal of Nanjing University of Posts and Telecommunications · 2010
Cognitive radio can effectively improve the utilization of spectrum through dynamic spectrum access technology,in which the channel selection affects directly the performance of the system.A novel channel selection algorithm is proposed based on the prediction of the probability of channel being idle.Simulation results have shown that the method can effectively reduce the collision rate between the primary and secondary users and thus reduce the interference of primary users caused by secondary users and the possibility of channel switching.
