Abstract :
In multiuser communication systems the exchange of some number of rate-limited messages both between encoders, and between decoders, can enlarge the achievable rate region. We consider interaction between a pair of Slepian-Wolf encoders, and a pair of deterministic broadcast channel decoders. For these systems, a single one-way message is sufficient. More generally, we make connections to relay channels and consider how to quantize data for relaying.
