Joint Source-Channel Coding for the Multiple-Access Relay Channel

Free registration required

Executive Summary

Reliable transmission of arbitrarily correlated sources over Multiple-Access Relay Channels (MARCs) and Multiple-Access Broadcast Relay Channels (MABRCs) is considered. In MARCs, only the destination is interested in a reconstruction of the sources, while in MABRCs, both the relay and the destination want to reconstruct the sources. The authors allow an arbitrary correlation among the sources at the transmitters, and let both the relay and the destination have side information that are correlated with the sources. Two joint source-channel coding schemes are presented and the corresponding sets of sufficient conditions for reliable communication are derived.
