Resumo

© 2019 IEEE.This paper presents an implementation of a realtime ISDB-TB LDM receiver in Software Defined Radio/GNU Radio Companion. The main idea of this work is to provide a hybrid digital TV broadcasting system that can be used as an option in a transition period between the current Brazilian system (ISDB-TB) and a possible new standard, such as a modified version of ATSC 3.0. The Core Layer is fully compatible with ISDB-TB and is multiplexed with an Enhanced Layer using a powerful channel coder, high order modulations and some other ATSC 3.0 features and techniques. With the use of the LDM in such systems, it is possible to deploy UHDTV applications. The implementation is done using the GNU Radio Companion software along with a Software Defined Radio platform to transmit and receive the Radio Frequency signal in real-time.
