Multiple-threshold scheme for cooperative spectrum sens-ing is investigated in this letter.The thresholds separate the energy value into several regions and each region is as-signed a fixed weight for data fusion.An algorithm is pro-posed to find the optimal thresholds that maximize the probability of detection for a given probability of false alarm.Compared to the traditional one bit hard combina-tion scheme and the equal gain combination(EGC)scheme,the proposed scheme achieves a good tradeoff between the sensing performance and overhead.
