| Abstract: | The studies of television frequency channel spectrum sensing focus on ATSC signal detection,adopted only by three countries so far.As for this,the widely used DVB-T signal is studied.DVB-T signal characteristics were analyzed,and then sensing techniques were investigated.Simulations were performed with spectrum sensing algorithms based on cyclic prefix.The results indicate that the proposed algorithms are shown to have very good detection and can satisfy the requirements of DVB-T signal detection. |
