Outline

In this paper, we propose a semantic communication framework based on diffusion model in a bandwidth-constrained environment. To improve the existing diffusion model-based generative models that do not consider bandwidth limitations, we integrate an advanced compression technique based on VAE to reduce the bandwidth requirement. The signal transmission process through the wireless channel is utilized as the forward process of the diffusion model, and at the receiver, the reconstructed features follow a Gaussian distribution through downsampling and dual upsampling modules. We derive the loss function of the proposed system and experimentally demonstrate that it outperforms the existing DJSCC method in terms of compression ratio and SNR by evaluating its performance using indices such as PSNR and LPIPS. The source code is open to the public.
