摘要:

语义交际被认为是对香农范式的突破,其目的是成功地传递信息源所传达的语义信息,而不是准确地接收每一个符号或比特,而不管其意义如何。本文提供了语义通信的概述。在简要回顾了Shannon信息论之后,我们讨论了深度学习支持的语义通信理论、框架和系统设计。与传统的通信系统的符号/比特出错率不同,本文还讨论了语义通信的性能指标。文章最后提出了语义通信中的几个开放性问题。

英文摘要:

Semantic communication, regarded as the breakthrough beyond the Shannon paradigm, aims at the successful transmission of semantic information conveyed by the source rather than the accurate reception of each single symbol or bit regardless of its meaning. This article provides an overview on semantic communications. After a brief review of Shannon information theory, we discuss semantic communications with theory, framework, and system design enabled by deep learning. Different from the symbol/bit error rate used for measuring conventional communication systems, performance metrics for semantic communications are also discussed. The article concludes with several open questions in semantic communications.
