No. of bitstreams: 2 VICTOR MORALES DIONISIO.pdf: 15019971 bytes, checksum: cc45d6dd4e5209047a4c19cbfbe5eb00 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Previous issue date: 2017-08-07 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / Fundo Mackenzie de Pesquisa / This paper presents the characteristics of two recent technologies on the scienti c and telecommunications community: the Advanced Television Systems Committee (ATSC) 3.0; the Software De ned Radio (SDR). Later, the usage of the three is studied by developing the modulator of the ATSC 3.0 system with SDR technique and the GNURadio Companion (GRC). In order to prove the integrity of the modulator implementation, the transmitted signal is tested with the Dektec receiver, composed by the DTA-2131 hardware and the Atsc3Xpress software. All the codes are developed in C++ language and the tests made in GRC. Such tests prove the integrity of the implementation since the receiver was able to demodulate the signal correctly, and that the SDR platform is a suitable tool for prototyping and researching digital TV transmission systems. / Este projeto apresenta as definições e características de duas tecnologias recentes na comunidade científica e de telecomunicações: o Advanced Television Systems Committee (ATSC) 3.0; o Rádio Definido por Software, do inglês Software Defined Radio (SDR). Posteriormente, investiga a combinação delas, desenvolvendo um modulador do sistema ATSC 3.0 por meio da técnica de SDR, utilizando o software GNURadio Companion (GRC). Com o intuito de comprovar a integridade da implementação do modulador, o sinal _e testado com o receptor, composto pelo hardware DTA-2131 e software Atsc3Xpress da Dektec. O desenvolvimento do sistema _e feito por meio de algoritmos computacionais em linguagem C++ e os testes são feitos no GRC. Tais testes comprovam a integridade da implementação uma vez que o receptor foi capaz de demodular o sinal corretamente, e que a plataforma de SDR _e uma ferramenta adequada para prototipagem e pesquisa de sistemas de transmissão de TV digital.
