- Double threshold energy detection based cooperative spectrum sensing exist the problem of perceived failure and need larger bandwidth to transmit cognitive users' perceive information. In this paper, we propose a method for two problems of spectrum sensing in cognitive radio networks (CRNs) aiming to increase the detection performance of the spectrum sensing. The method can dynamically change the threshold value according to the perceived result of the previous time, and then determine the existence state of the primary user when the energy value is between the high and low threshold values. Twice-cooperative spectrum sensing based on double threshold energy detection can reduce the perceive information transferred to the fusion decision center and save the transmission bandwidth. The simulation results show that this method can effectively improve the detection probability of cooperative spectral sensing and reduce the probability of missed detection.
