Abstract :
Detection performance is very important for spectrum sensing in CR systems. A collaborative spectrum sensing algorithm, which is based on double-threshold energy detection for Rayleigh fading channels, is proposed in this paper. Theoretical analysis and simulation results show that this double-threshold based algorithm can improve the performance more significantly than conventional collaborative spectrum sensing algorithms.
