A Novel Spectrum Prediction Algorithm for Cognitive Radio System Based on Chaotic Neural Network ⋆

In the cognitive radio system, the rationalization of spectrum allocation can be improved by the spectrum prediction algorithm. In recent years, the researches of spectrum prediction focus on how to predict channel status. In order to improve spectrum utilization and reduce frequency of channel switching, a novel spectrum prediction mechanism is designed, which use Chaos Neural Network to analyze and predict duration of channel status. The effectiveness of the new mechanism is proved through the extensive simulation.
