Implementation of an 8K-DTV broadcast system using SDR

Abstract

This paper presents an implementation of an 8K-DTV transmitter and receiver in Software Defined Radio/GNU Radio Companion. The main idea of this work is to provide a modified digital TV broadcast system, based on the Brazilian system (ISDB-T B), using two adjacent channels of 6 MHz, channel bonding technique, soft-decision demapper, powerful channel coding and high order modulations, to achieve high bit rates and allow the transmission and reception of content in Ultra High Definition (8K) using indoor antennas. 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.
