Cooperative spectrum sensing using frequency domain correlation detection

This paper presents a cooperative spectrum sensing scheme for cognitive radio based on the FFT energy detection. The proposed cooperative sensing scheme utilizes the cross correlation between the output of the sensor of interest and composite output of other sensors. Simulation results show that the...

Description
Summary:This paper presents a cooperative spectrum sensing scheme for cognitive radio based on the FFT energy detection. The proposed cooperative sensing scheme utilizes the cross correlation between the output of the sensor of interest and composite output of other sensors. Simulation results show that the proposed cooperative sensing scheme is superior to conventional cooperative sensing using frequency domain correlation detection.
