DMCE: Diffusion Model Channel Enhancer for Multi-User Semantic Communication Systems

no code implementations29 Jan 2024 Youcheng Zeng, Xinxin He, Xu Chen, Haonan Tong, Zhaohui Yang, Yijun Guo, Jianjun Hao

To address this, this paper proposes a diffusion model (DM)-based channel enhancer (DMCE) for improving the performance of multi-user semantic communication, with the DM learning the particular data distribution of channel effects on the transmitted semantic features.

Importance-Aware Image Segmentation-based Semantic Communication for Autonomous Driving

no code implementations16 Jan 2024 Jie Lv, Haonan Tong, Qiang Pan, Zhilong Zhang, Xinxin He, Tao Luo, Changchuan Yin

Therefore, we propose a vehicular image segmentation-oriented semantic communication system, termed VIS-SemCom, where image segmentation features of important objects are transmitted to reduce transmission redundancy.
