Spectrum sensing is a crucial technology in Cognitive Radio (CR) system. The performance of spectrum detection can be improved by utilizing spatial diversity of multiple antennas or cooperative detection of multiple Secondary Users (SUs). Without the prior information provided by Primary Users (PUs), the combining signal means of multiple antennas in the frequency domain is analyzed in the paper. The simulation results show that the performance of multi-antenna spectrum detection is improved through the Maximal-Ratio Combining of spectrum correlation function.
