STCC: A Unified Source-Channel Semantic Token Coding Framework for Semantic Communications
Zhicheng Bao, Chen Dong, Sen Wang +6
Deep Joint Source-Channel Coding (JSCC) has emerged as a promising paradigm for overcoming the ``cliff effect" in wireless communications. However, existing Deep JSCC frameworks op…
Breaking Semantic-Aware Watermarks via LLM-Guided Coherence-Preserving Semantic Injection
Zheng Gao, Xiaoyu Li, Zhicheng Bao +2
Generative images have proliferated on Web platforms in social media and online copyright distribution scenarios, and semantic watermarking has increasingly been integrated into di…
Conquering High Packet-Loss Erasure: MoE Swin Transformer-Based Video Semantic Communication
Lei Teng, Senran Fan, Chen Dong +5
Semantic communication with joint semantic-channel coding robustly transmits diverse data modalities but faces challenges in mitigating semantic information loss due to packet drop…
Semantic Feature Decomposition based Semantic Communication System of Images with Large-scale Visual Generation Models
Senran Fan, Zhicheng Bao, Chen Dong +3
The end-to-end image communication system has been widely studied in the academic community. The escalating demands on image communication systems in terms of data volume, environm…
Semantic Similarity Score for Measuring Visual Similarity at Semantic Level
Senran Fan, Zhicheng Bao, Chen Dong +3
Semantic communication, as a revolutionary communication architecture, is considered a promising novel communication paradigm. Unlike traditional symbol-based error-free communicat…
sDAC -- Semantic Digital Analog Converter for Semantic Communications
Zhicheng Bao, Chen Dong, Xiaodong Xu
In this paper, we propose a novel semantic digital analog converter (sDAC) for the compatibility of semantic communications and digital communications. Most of the current semantic…
