Evolving Token Communication with Parametric Memory Network
Weixuan Chen, Qianqian Yang
Token communication has emerged as a promising framework for efficient wireless transmission by representing source data as compact semantic tokens. However, transmitting full sema…
OmniEncoder: See, Hear, and Feel Continuous Motion Like Humans With One Encoder
Detao Bai, Shimin Yao, Weixuan Chen +4
Recent advances in omni-modal large language models have enabled remarkable progress in joint vision-audio understanding. However, prevailing architectures rely on modality-specifi…
Secure Digital Semantic Communications: Fundamentals, Challenges, and Opportunities
Weixuan Chen, Qianqian Yang, Yuanyuan Jia +5
Semantic communication (SemCom) has emerged as a promising paradigm for future wireless networks by prioritizing task-relevant meaning over raw data delivery, thereby reducing comm…
Privacy-Preserving Semantic Communication over Wiretap Channels with Learnable Differential Privacy
Weixuan Chen, Qianqian Yang, Shuo Shao +3
While semantic communication (SemCom) improves transmission efficiency by focusing on task-relevant information, it also raises critical privacy concerns. Many existing secure SemC…
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…
