On Practical Design for Joint Distributed Source and Network Coding
The authors consider the problem of communicating correlated information from two source nodes over a network to multiple destination nodes. This problem involves a joint consideration of distributed source coding (compression) and network coding (information relaying). Although the optimal admissible rate region was previously characterized, it was not yet clear how to design practical communication schemes with low complexity. This paper provides a partial answer to this question. Specially, they focus on the case where the two sources are related by a Binary Symmetric Channel (BSC).
