Design and Simulation of DVB-T2 Transmitter

Abstract

Digital video broadcasting, DVB has become the synonym of digital television as well as data broadcasting. The DVB Project was launched on the 10th of September, 1993. DVB systems distribute data using a variety of approaches. These approaches include: satellite, cable and terrestrial television. These three sub-standards are basically differ in the specifications of the physical representation, modulation, transmission as well as reception of the signal. DVB-T is the consortium standard for broadcast transmission of digital terrestrial television. The key motivation behind this standard was the desire in several European countries to offer high definition television (HDTV) services as efficiently and effectively as possible.DVB-T2 is considered to be the modified version of DVB-T.DVB-T2 leads to performance improvement by introducing state-of-the art communication techniques where it achieves 30% better capacity compared with DVB-T. In some cases, the data rate will be up to 50% higher under comparable conditions. In this paper we demonstrate the architecture of the DVB-T2 system, as well as a MATLAB design and simulation of the DVB-T2 transmitter. The transmitter model is then tested for different data rates. The model provides an overall evaluation of the DVB-T2 transmitter parameters and can be used for educational and testing purposes.
