Representation of Correlated Sources Into Graphs for Transmission Over Broadcast Channels

In this paper, the authors consider the communication problem that involves transmission of correlated sources over broadcast channels. They consider a graph-based framework for this information transmission problem. The system involves a source coding module and a channel coding module. In the source coding module, the sources are efficiently represented using a nearly semi-regular bipartite graph, and the in the channel coding module, the edges of this graph are reliably transmitted over a broadcast channel. They consider nearly semi-regular bipartite graphs as discrete interface between source coding and channel coding in this multi-terminal setting.
