Cognitive radio (CR) is viewed as a promising approach to improving the utilization of the radio spectrum. It is a wireless communication technology, which has the capability of sensing and utilizing the underutilized spectrum resources. Recognizing idle spectrum efficiently is a key function for cognitive radio (CR) and requires high precision and fast signal processing technique. Sensitivity to noise uncertainty is limitation of current spectrum sensing strategies in CR networks. In this… CONTINUE READING
