Spectrum sensing is an essential concept in cognitive radio. It exploits the inefficient utilization of radio frequency spectrum without causing destructive interference to the licensed users. In this paper we considered spectrum sensing of Digital Video Broadcast Terrestrial (DVB-T) signal in different scenario. We compared various spectrum sensing algorithms that make use of the second order statistics; the energy detector was also included for comparison. The results show that it is possible to obtain good detection performance by exploiting the correlation method.
