Abstract
► Applying fuzzy hypothesis test model for noise power uncertainty in cognitive radio. ► Deploying likelihood ratio test on the fuzzy model for local Spectrum Sensing (SS). ► The threshold values of local SS detectors are computed and tabulated offline. ► Using a fusion center for combining local hard decisions for Cooperative SS (CSS). ► The proposed method outperforms the simple and bi-thresholds energy detectors in CSS.
