Digital video broadcasting is used for digital television transmission, which is based on moving pictures expert group (MPEG-2) video compression. The DVB standards are classified into three categories of traditional broadcast networks which are DVB – S for satellite network, DVB – C for cable network, DVB – T for terrestrial network. The digital terrestrial television supports two types of services which are DVB-T and DVB-T2. DVB-T2 is considered as the most advanced digital terrestrial television system. It supports high-definition television (HDTV) services using same frequency spectrum, and better performances in mobile environments. Furthermore, in June 2014, version-1 of DVB-T2 Integrated Receiver Decoder (IRD) technical specification for ASEAN countries was released with the objective of reaping the benefits of economies of scale for affordable DVB-T2 IRDs so as to facilitate the adoption of digital TV in ASEAN members’ countries. However, one of the challenges of the DVB-T2 is the many options it provides in system mode and parameters which needs to be accurately selected to suit different applications. In view of this, this project studied and investigated through simulation the BER versus SNR performance for the IRD specification. This includes the different types of channels: Gaussian, Rician and Rayleigh. In addition simulations for different scenarios were carried out for cases of different guard interval, code rates, effect of constellation rotation in different modulation schemes. The common software platform (CSP) developed for simulation of the DVB-T2 and Matlab 2014 was used in carrying out the simulations. The result of simulation showed the different BER versus C/N performance of the IRD specification. From the results, it can be seen that the IRD can be used for different kinds of services and can support both fixed and portable devices based on selected scenario or system requirements.
