Abstract(in English) In IEEE 802.22 wireless regional area network system, the signal detection method is required for identifying the occupied and unoccupied TV channels. In this paper, we consider the signal detection method which is based on cyclostationary processing. Based on this processing, cyclic spectrum estimation of NTSC and ISDB-T signals are generated. The decision of occupied or unoccupied of the signals are based on searching of the peak values of the spectral redundancy at one of the cyclic frequencies. With several values of signal-to-noise ratio (SNR), the cyclic spectrum based detection are investigated.
