Resumo
© 2015 IEEE.Software-Defined Radio (SDR) has become a great tool for fast prototyping and developing new devices for communications systems as well as for implementing flexible, multi-standards communication equipment. In the same pace, Digital Terrestrial Television Broadcasting (DTTB) has become ubiquitous throughout the world and is continuously in development. Integrated System Digital Broadcasting Terrestrial version B (ISDB-TB) uses Band Segmented Transmission - Orthogonal Frequency Division Multiplexing (BST-OFDM), and a powerful channel code and interleavers. In this article, a new implementation of ISDB-TB modulator with SDR is proposed to achieve real time transmission fully compliant with the ISDB-TB standards. Also the computational performance characteristics of each processing block is presented to compare the total CPU consumption used. The software was developed in the GNU Radio and is a valuable tool in research and educational fields of digital communication.
