Spectrum sensing is one of the main parts in cognitive radio. The performance of the adopted spectrum sensing method is very important. When the primary user and the cognitive radio are in operation simultaneously, performance of spectrum sensing is damaged. We propose to apply the linear prediction for the blind source separation algorithm as an alternative for more conventional techniques. Simulation...
In currently cooperative spectrum sensing, each secondary user requires some information in order to achieve the vacant spectrum sensing. Energy detection is commonly used in local spectrum sensing. However, performance of cooperative spectrum sensing based on energy detection is damaged due to the noise uncertainty in realistic environment. In this paper, blind source separation algorithm is introduced...
