Abstract

The cognitive users can use the spectrum holes which are vacant at some time or some frequency. Once the authorized users need to use the spectrum again, the cognitive users should stop using it to avoid interfering primary users. In this paper, a method based on active learning (AL) and AdaBoost machine (ABM) for the primary user signal modulation type recognition is proposed in low signal to noise ratio. A set of cyclic spectrum features are first calculated, and the training samples and testing samples are formed for classification. Then, active learning algorithm is applied to obtain samples improved classification through a number of iterations, and AdaBoost is formed. Finally, the formed SVM is utilized to recognize the primary user signal modulation type. The simulation results shows that the proposed AL-ABM Algorithm can improve the recognition accuracy of signal samples obviously.
