Transmission of Correlated Sources Over a MAC: A Gaussian Approximation-Based Analysis

The problem of separately encoding and subsequently transmitting correlated sources over a discrete memoryless multiple-access channel is revisited. In particular, the authors examine the sufficient conditions on the source and the channel under which there exists a n-length block code satisfying the condition that the error probability of reconstructing the discrete memoryless multiple source is no larger than some fixed constant lossless transmission. They modify the decoding rule of Cover-El Gamal-Salehi and analyze the error probability using Gaussian approximations to derive a second order generalization their sufficient condition for the lossless transmission of the correlated sources.
