Cross-correlation metrics introduce a challenging performance for multiple antennas spectrum sensing in cognitive radio networks, since it permits to alleviate the drawback of the energy based approaches under low SNR and noise level uncertainty, while maintaining the low complexity. In this paper, we propose a novel sensing approach based on a linear soft weighting of the Combined Second Order Moment...
Spectrum sensing presents a substantial challenge in the novel emerging telecommunications technologies, and a crucial step that should be performed by cognitive user to identify the unoccupied frequency bands, in order to enhance the spectral efficiency and the QoS to both licensed and unlicensed users. In this paper, we propose a novel sensing approach based on the cross-correlated moments' selection...
