Entropy-and-Channel-Aware Adaptive-Rate Semantic Communication with MLLM-Aided Feature Compensation
Weixuan Chen, Qianqian Yang, Yuhao Chen +4
Despite the transmission efficiency gains of semantic communication (SemCom) over traditional methods, most existing SemCom schemes still operate at a fixed transmission rate regar…
A DRL-Empowered Multi-Level Jamming Approach for Secure Semantic Communication
Weixuan Chen, Qianqian Yang
Semantic communication (SemCom) aims to transmit only task-relevant information, thereby improving communication efficiency but also exposing semantic information to potential eave…
Can Knowledge Improve Security? A Coding-Enhanced Jamming Approach for Semantic Communication
Weixuan Chen, Qianqian Yang, Shuo Shao +4
As semantic communication (SemCom) attracts growing attention as a novel communication paradigm, ensuring the security of transmitted semantic information over open wireless channe…
CASC: Condition-Aware Semantic Communication with Latent Diffusion Models
Weixuan Chen, Qianqian Yang
Diffusion-based semantic communication methods have shown significant advantages in image transmission by harnessing the generative power of diffusion models. However, they still f…
