Learned Image Transmission with Hierarchical Variational Autoencoder

no code implementations29 Aug 2024 Guangyi Zhang, Hanlei Li, Yunlong Cai, Qiyu Hu, Guanding Yu, Runmin Zhang

In this paper, we introduce an innovative hierarchical joint source-channel coding (HJSCC) framework for image transmission, utilizing a hierarchical variational autoencoder (VAE).

Deep Refinement-Based Joint Source Channel Coding over Time-Varying Channels

no code implementations26 Nov 2023 Junyu Pan, Hanlei Li, Guangyi Zhang, Yunlong Cai, Guanding Yu

This specialization poses a limitation, as their performance tends to wane in practical scenarios marked by highly dynamic channels, given that a fixed SNR inadequately represents the dynamic nature of such channels.
