Distributed Reed-Solomon Codes for Simple Multiple Access Networks (1310.5187v1)

Abstract: We consider a simple multiple access network in which a destination node receives information from multiple sources via a set of relay nodes. Each relay node has access to a subset of the sources, and is connected to the destination by a unit capacity link. We also assume that $z$ of the relay nodes are adversarial. We propose a computationally efficient distributed coding scheme and show that it achieves the full capacity region for up to three sources. Specifically, the relay nodes encode in a distributed fashion such that the overall codewords received at the destination are codewords from a single Reed-Solomon code.
