Contribution

It introduces a new semantic channel model with multiple input and output memories, advancing the analysis of zero-error capacity in channels with memory.

Findings

Semantic channels with memory have higher zero-error capacities.

Memory impacts the capacity and error-free communication strategies.

The framework offers a detailed understanding of semantic channel behavior.

Abstract

This paper investigates the zero-error capacity of channels with memory. Motivated by the nuanced requirements of semantic communication that incorporate memory, we advance the classical enlightened dictator channel by introducing a new category known as the semantic channel. We analyze the zero-error capacity of the semantic channel using a comprehensive framework that accommodates multiple input and output memories. Our approach reveals a more sophisticated and detailed model compared to the classical memory channels, highlighting the impact of memory on achieving error-free communication.
