Digital broadcast systems have increasingly been deployed for various services such as Digital Video Broadcasting (i.e. DVB-S, DVB-T, etc.) and Digital Audio Broadcasting (DAB). Classical digital broadcast systems were designed with fixed modulation guarantee reliable communication even with very hostile channel environment.  DVB-T2 terrestrial television standard is becoming increasingly important.  The emergence of it is motivated by the higher spectral efficiency and adopting  transition from analogue TV to DVB-T2, or transition from DVB-T to DVB-T2. It can reduce the transmission cost per program and deliver HD services economically viable. It introduces a new technique to improve performance in channels with frequency selective fading. If in addition improved source coding (MPEG-4) is employed, the gain in broadcast transmission is remarkable.
