Abstract :
A weighted energy detector and correlated-generalised likelihood ratio test detector are proposed for spectrum sensing assisted with correlated multiple antennas in cognitive radio. Simulations are presented to show that the detection performance of the proposed algorithms is improved significantly in the correlated antennas scenario.
