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