Semantic communication (SemCom) aims to convey the meaning behind a transmitted
message by transmitting only semantically-relevant information. This semantic-centric …

Semantic communication has served as a novel paradigm and attracted a broad interest
from researchers. One critical aspect of it is the multi-user semantic communication theory …

Semantic communications have emerged as a new paradigm for improving communication
efficiency by transmitting the semantic information of a source message that is most relevant …

Recently, there has been a growing interest in learning-based semantic communication
because it can prioritize the preservation of meaningful semantic information over the …

Diffusion models (DM) can gradually learn to remove noise, which have been widely used in
artificial intelligence generated content (AIGC) in recent years. The property of DM for …

In the coming sixth generation (6G) communication era, to provide seamless and ubiquitous
connections, the space-air-ground-sea integrated network (SAGSIN) is envisioned to …

Although humans have five basic senses, sight, hearing, touch, smell, and taste, most
multimedia systems in current systems only capture two of them, namely, sight and hearing …

Semantic communication (SemCom) has received considerable attention for its ability to
reduce data transmission size while maintaining task performance. However, existing works …

In this paper, we propose a novel joint source-channel coding (JSCC) approach for channel-
adaptive digital semantic communications. In semantic communication systems with digital …

This paper addresses the challenge of achieving information-theoretic security in semantic
communication (SeCom) over a wiretap channel, where a legitimate receiver coexists with …
