| Sumario: | This essay presents theoretical concepts of the Brazilian Digital TV System (SBTVD) and Software De ned Radio (SDR). The purpose of this essay is to implement timing synchronization stages and a channel estimator to enable ISDB-TB reception via RF. Thus, enabling the analysis of the constellations of the received signals. To achieve this goal, it was used SDR concepts and the C++ and Python programming languages. Through the use of the GNU Radio tool, time, frequency and OFDM frame synchronization were implemented. Besides that, a channel estimator was also implemented Computer simulations were carried out to verify the performance of the implementations. |
