Low-Latency Generative Semantic Communication via Channel-Realization Flow Matching
Fan Gao, Youzheng Wang, Zhijin Qin +1
Generative semantic communication receivers deliver high perceptual quality but suffer from prohibitive decoding latency. This bottleneck arises because diffusion receivers rely on…
Image Semantic Communication with Quadtree Partition-based Coding
Yinhuan Huang, Zhijin Qin
Deep learning based semantic communication (DeepSC) system has emerged as a promising paradigm for efficient wireless transmission. However, existing image DeepSC methods, frequent…
Diffusion-enabled Secure Semantic Communication Against Eavesdropping
Boxiang He, Zihan Chen, Fanggang Wang +3
In this paper, AN is introduced into semantic communication systems for the first time to prevent semantic eavesdropping. However, the introduction of AN also poses challenges for…
Cross-Layer Security for Semantic Communications: Metrics and Optimization
Lingyi Wang, Wei Wu, Fuhui Zhou +2
Different from traditional secure communication that focuses on symbolic protection at the physical layer, semantic secure communication requires further attention to semantic-leve…
A Secure and Efficient Distributed Semantic Communication System for Heterogeneous Internet of Things
Weihao Zeng, Xinyu Xu, Qianyun Zhang +4
Semantic communications are expected to improve the transmission efficiency in Internet of Things (IoT) networks. However, the distributed nature of networks and heterogeneity of d…
IRS-Enhanced Secure Semantic Communication Networks: Cross-Layer and Context-Awared Resource Allocation
Lingyi Wang, Wei Wu, Fuhui Zhou +2
Learning-task oriented semantic communication is pivotal in optimizing transmission efficiency by extracting and conveying essential semantics tailored to specific tasks, such as i…
