A novel in-band spectrum sensing method based on guard frequency bandwidth for cognitive OFDM systems is proposed in this paper. The proposed spectrum sensing procedure is based on leakage-negligible-BW, on which power detection or other detection methods can be implemented. The advantage of this in-band sensing method is the impact to OFDM system frame structure could be minimized.
