Achievable rates for multiple-access channels with correlated messages

In this paper, the multiterminal sources is mapped independently into a message set characterized by a graph which preserves a predetermined amount of correlation between the sources, and the message set becomes the input to channel encoder. In this work joint source-channel coding scheme is considered as a part with associated message graph for transmitting distributed correlated sources over MAC. Thus the parameters are allowed to increase exponentially with number of channels and the performance of this characterized set is measured using minimum average probability of error.
