Abstract

A cooperative spectrum sensing technique in cognitive radio (CR) networks is proposed in this paper, which is based on the data fusion of different stochastic resonance (SR) energy detectors. Due to the noisy uncertainty in the unpredictable wireless communication channel, the detection performance of the traditional energy detector cannot be guaranteed. By introducing the SR system with different SR noise types, and with the fusion on these SR-based energy detectors, the detection probability can be improved even under low signal-to-noise ratio (SNR) circumstances. Computer simulation results validate the efficiency of the proposed novel cooperative spectrum sensing approach.
