Transmission of Correlated Sources Over Multi-user Channels

Source and channel coding over multi-user channels in which receivers have access to correlated source side information, is considered. For several simple multi-user channels necessary and sufficient conditions are characterized for lossless transmission under certain source-channel structures. In particular, the multiple access channels, the compound multiple access channels and the interference channels with correlated sources and correlated receiver side information are considered. In all of the cases for which the optimal source-channel matching conditions have been identified, this optimal performance is shown to be achieved by separately designed source and channel codes.
