Joint Source-Channel Coding on a Multiple Access Channel With Side Information

Free registration required

Executive Summary

The authors consider the problem of transmission of several distributed correlated sources over a Multiple Access Channel (MAC) with side information at the sources and the decoder. Source-channel separation does not hold for this channel. Sufficient conditions are provided for transmission of sources with a given distortion. The source and/or the channel could have continuous alphabets (thus Gaussian sources and Gaussian MACs are special cases). Various previous results are obtained as special cases. They also provide several good joint source-channel coding schemes for discrete sources and discrete/continuous alphabet channel.
