This paper presents the cooperative spectrum sensing in cognitive radio networks under spatially correlated noise. A suboptimal fusion rule which has negligible performance loss and less implementation complexity compared to the optimal fusion rule is proposed. Furthermore, the asymptotic detection probability of the proposed fusion rule in a linear array cognitive radio network is investigated. Finally, simulation results are provided to verify these analytical results.
