Abstract

An Application Layer - Forward Error Correction (AL-FEC) scheme for mobile reception for the Brazilian Digital Television System (SBTVD) is proposed. The mobile reception in the SBTVD is not as effective due to the Doppler effect that occurs when the user is moving. In order not to modify standards already established, it is proposed to implement an AL-FEC scheme based on Raptor codes as a software upgrade in the SBTVD. Simulation results show that proposed scheme provides coding gain with a relatively low cost implementation
