A key enabling functionality in implementing Cognitive Radio is to reliably detect the licensed users. In recent literature, cooperation among spectrum sensing terminals is suggested to offer reliable sensing performance. We consider the problem that the presence of malfunctioning or malicious sensing terminals will severely degrade the performance of cooperative spectrum sensing. In this paper, we extend the Weighted Sequential Probability Ratio Test (WSPRT) by replacing the binary local report with N-bits local report to achieve a better detection performance. Additionally, three types of reputation rating evaluation schemes are introduced: neutral, punitive and heavy punitive. Simulation results show that the extended WSPRT technique improves detection performance. Moreover, the extended WSPRT with heavy punitive scheme is shown to be the most robust against the malfunctioning or malicious sensing terminals.
