Abstract :
In the year 2005 the Brazilian government supported many research consortia in order to develop an advanced digital television system employing the most recent technologies for multimedia broadcasting. One of the proposals for the physical layer of this system was entitled innovative modulation for the Brazilian digital TV system (MI-SBTVD). The MI-SBTVD project includes high performance error correcting codes, transmit spatial diversity and multi-carrier modulation. The aim of this paper is to present an overview of this innovative modulation system. The building blocks of the system, its characteristics and most relevant innovations are presented. The performance of the whole system under different channels is compared with the performance of the present-day digital television standards
