摘要:

语义通信旨在传输执行给定任务所需的基本信息,以提高通信效率。基于深度学习的联合源信道编码(deep JSCC)已成为语义通信系统的一种有前途的方法;然而,其性能在部署信道与训练信道条件不同时往往会退化,使得鲁棒性成为关键要求。本文提供了一个结构化的综述,概述了最近增强深度JSCC鲁棒性的方法。具体而言,现有方法分为两类:鲁棒训练方法和自适应方法,后者进一步分为自适应语义特征选择、物理层自适应和语义特征自适应。最后,我们讨论了有前途的方向,包括多任务泛化和可解释性在鲁棒语义通信系统中的应用。

英文摘要:

Semantic communications (SCs) aim to transmit only the essential information required to perform given tasks, thereby improving communication efficiency. Deep learning-based joint source-channel coding (deep JSCC) has emerged as a promising approach for SC systems; however, its performance often degrades when the deployment channels differ from the training channel conditions, making robustness a critical requirement. This paper presents a structured overview of recent methodologies for enhancing the robustness of deep JSCC. Specifically, existing approaches are categorized into two classes: robust training approaches and adaptive approaches, with the latter further divided into adaptive semantic feature selection, physical-layer adaptation, and semantic feature adaptation. Finally, we discuss promising directions, including multi-task generalization and explainability in robust SC systems.
