Previous issue date: 2017-02-20 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / 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. / Este trabalho apresenta uma descricão sobre o Sistema Brasileiro de TV Digital (SBTVD)
e Software De fined Radio (SDR). O objetivo deste trabalho é implementar um estimador
de canal e estágios de sincronismo para receber sinais ISDB-TB via RF. Com isso, sendo
possível a análise das constelacões dos sinais recebidos. Para tal, foram utilizados conceitos
de SDR e as linguagens de programacão C++ e Python. Por meio da ferramenta
aberta GNU Radio, foram realizadas implementacões de sincronismo no tempo, frequência
(inteira e fracionária) e de quadro OFDM. Além disso, um estimador de canal foi implementado.
Simulacões computacionais foram realizadas para veri ficar o funcionamento das
implementacões.
