This paper deals with the design of coding schemes for transmitting a source over a broadcast channel when there is source side information at the receivers. Based on Slepian-Wolf coding over broadcast channels, three hybrid digital/analog schemes are proposed and their power-distortion tradeoff is investigated for Gaussian sources and Gaussian broadcast channels. All three transmit the same digital and analog information but with varying coding order. Although they are not provably optimal in general, they can significantly outperform uncoded transmission and separate source and channel coding. © 2008 IEEE.

Abstract
This paper deals with the design of coding schemes for transmitting a source over a broadcast channel when there is source side information at the receivers. Based on Slepian-Wolf coding over broadcast channels, three hybrid digital/analog schemes are proposed and their power-distortion tradeoff is investigated for Gaussian sources and Gaussian broadcast channels. All three transmit the same digital and analog information but with varying coding order. Although they are not provably optimal in general, they can significantly outperform uncoded transmission and separate source and channel coding. © 2008 IEEE.Pubblicazioni consigliate
