摘要：In this paper, a cooperative sensing algorithm for OFDM is proposed in this paper based on the performance analysis of ONPD algorithm, then the system weight vector is optimized and the closed form expression of optimal weight vector is obtained using the maximum improved deflection coefficient. Theoretical analysis and simulation results demonstrate the remarkable improvement of proposed algorithm on detection performance compared with the classical cooperation detection algorithm.
