Abstract

A cooperative spectrum sensing scheme is proposed where the energy detector has multiples of verification using time delay in cognitive radio system. The performance under Suzuki channel environment is investigated by simulation and compared to that of a cooperative spectrum sensing with conventional energy detector. Simulation results show that the proposed scheme improves the SNR performance to get 0.01 of misdetection probability, when false alarm probability is assumed to 0.1. Additionally, it is shown that with the cooperative user number of two the proposed cooperative scheme may achieve the similar performance compared to the conventional cooperative scheme with the cooperative user number of four. The performance is also described in terms of ROC curve in order to confirm the results.
