—We propose a novel spectrum-sensing method for cognitive radio (CR) based on stochastic resonance (SR). The spectral power of primary users (PUs) can be amplified, and the signal-to-noise ratio (SNR) of a received signal can be increased using SR. This ensures that the detection probability of the proposed approach is higher than that of the traditional(More)
—Energy sense of adaptive double threshold joint spectrum perception algorithm using multiple cognitive, and after double threshold for comprehensive judgment, and threshold value with the discretion of the signal to noise ratio (SNR) adaptive adjustment, will eventually each SU decision data fusion center for spectrum using the information, make perception(More)
A new censoring cooperative spectrum sensing scheme based on stochastic resonance (SR) technique in cognitive radio (CR) network is proposed in this paper. The observations of the cooperative secondary users (SUs) whose statistics fall into the censoring interval are processed by SR system in the proposed scheme. The hard fusion and the soft fusion for the(More)
