Abstract

This paper introduces TranGDeepSC, a lightweight CNN-based deep semantic communication (DeepSC) system that leverages Vision Transformer (ViT) knowledge through co-training to enhance image transmission. Evaluated on CIFAR-100 across various SNRs, TranGDeepSC demonstrates competitive performance with ViTDeepSC, and outperforms SemViT and ADJSCC-V in image quality, particularly in low-SNR environments. Notably, it offers substantial gains in efficiency: 92.8% fewer parameters than ADJSCC-V, 72.0% lower energy use, and 48% faster processing than ViTDeepSC. These advantages make TranGDeepSC well-suited for resource-constrained applications in next-generation communication systems, including 6G, IoT, and real-time multimedia streaming.

TranGDeepSC：在基于cnn的语义通信系统中利用ViT知识

本文介绍了基于cnn的轻量级深度语义通信（DeepSC）系统TranGDeepSC，该系统通过协同训练利用视觉变换（Vision Transformer, ViT）知识来增强图像传输。在各种信噪比的CIFAR-100上进行评估，TranGDeepSC与ViTDeepSC表现出竞争优势，在图像质量方面优于SemViT和ADJSCC-V，特别是在低信噪比环境下。值得注意的是，它提供了显著的效率提升：与ADJSCC-V相比，参数减少92.8%，能耗降低72.0%，处理速度比ViTDeepSC快48%。这些优势使TranGDeepSC非常适合下一代通信系统中资源受限的应用，包括6G、物联网和实时多媒体流。
