摘要:

语义沟通被认为是对香农范式的突破,香农范式只传递语义信息,显著提高了沟通效率。本文介绍了一种广义语义通信系统的框架,它利用多模态信源和无线信道环境中的语义信息。随后,通过两个示例展示了所开发的深度学习使能的端到端语义通信和环境语义辅助的无线通信技术。文章最后提出了促进这种广义语义通信系统发展的几个研究挑战。

英文摘要:

Semantic communication is regarded as the breakthrough beyond the Shannon paradigm, which transmits only semantic information to significantly improve communication efficiency. This article introduces a framework for generalized semantic communication system, which exploits the semantic information in both the multimodal source and the wireless channel environment. Subsequently, the developed deep learning enabled end-to-end semantic communication and environment semantics aided wireless communication techniques are demonstrated through two examples. The article concludes with several research challenges to boost the development of such a generalized semantic communication system.
