- In this paper, we propose two novel data fusion schemes for cooperative spectrum sensing in the IEEE 802.22 WRAN system. The data fusion structure is proper for the WRAN system due to its centralized structure, and it can provide reliable sensing performance. The proposed data fusion schemes improve the sensing reliability by utilizing confidence vector of the sensing result. Moreover, application with statistic weight on the confidence vector provides additional performance gain. The computer simulation results show that the proposed data fusion methods guarantee better sensing performance than the conventional data fusion algorithms. ©2009 IEEE.
