Zero vs. epsilon Error in Interference Channels

TL;DR

This paper investigates the impact on communication rates when requiring zero error in interference channels, contrasting with traditional approaches that accept a small error probability, motivated by network coding considerations.

Contribution

It provides a quantitative analysis of the rate loss incurred by insisting on zero error in interference channels, a novel focus in the field.

Findings

Zero error constraints cause significant rate loss compared to vanishing error models

Quantitative bounds on the rate difference are established

Implications for network coding and reliable communication strategies

Abstract

Traditional studies of multi-source, multi-terminal interference channels typically allow a vanishing probability of error in communication. Motivated by the study of network coding, this work addresses the task of quantifying the loss in rate when insisting on zero error communication in the context of interference channels.
