Description	Spectrum sensing is an essential part of the cognitive radio systems which can be the solution for radio spectrum shortage. There are various methods of the signal detection; many of them are based on the energy detector. Another group of methods is based on known detected signal parameters as the method for DVB-T signal detection described in this paper. Because DVB-T uses OFDM with cyclic prefix, the computation of cyclic prefix correlation and the consequent correlation function level monitoring are proposed. The simulations of this method and their results are described in the paper. Test DVB-T signal with various C/N ratios is obtained by sampling of the output of the vector signal generator and complete signal processing is implemented in Matlab with Parallel Computing Toolbox support. The performance of investigated method for DVB-T signal detection is discussed in the paper.
