英文摘要	Spectrum detection for vacant bands is one of the key techniques in cognitive radio (CR) systems. Cooperative detection outperforms single user detection in many aspects. The existence of malicious user could severely degrade the performance of cooperative CR systems. In this paper, a new cooperative detection scheme with malicious user suppression is proposed, which has lower complexity and better performance compared with the existing one. Simulation results show that when 25% users in the system are malicious, our proposed method can introduce more improvement of missed detection probability by nearly 20%. ?2009 IEEE.; EI; 0
