On Achievable Rates for Non-Linear Deterministic Interference Channels

TL;DR

This paper explores the extension of interference alignment techniques to non-linear deterministic interference channels, demonstrating that alignment remains effective and often optimal for achieving degrees of freedom in these complex models.

Contribution

It introduces the application of interference alignment to non-linear deterministic channels and establishes conditions for optimal degrees of freedom achievement.

Findings

Alignment extends naturally to non-linear deterministic channels

Achieved degrees of freedom are often optimal in these models

The approach broadens the applicability of interference alignment techniques

Abstract

This paper extends the literature on interference alignment to more general classes of deterministic channels which incorporate non-linear input-output relationships. It is found that the concept of alignment extends naturally to these deterministic interference channels, and in many cases, the achieved degrees of freedom (DoF) can be shown to be optimal.
