Leveraging Stable Diffusion with Context-Aware Prompts for Semantic Communication
Bibliographic record
Abstract
Semantic communication in wireless image transmission leverages the meaning embedded in the image data, aiming to compress, transmit, and reconstruct images based on their semantic content rather than purely pixel data. This paradigm shift allows more efficient utilization of bandwidth and computational resources, focusing on extracting key features and contextual information that is critical for ensuring that the essential content of the image is preserved and accurately conveyed. In this study, we present a novel Stable Diffusion-based semantic communication (SDSC) framework that demonstrates high performance, characterized by an elevated bandwidth compression ratio (BCR) and robust noise tolerance achieved by diffusion mechanism integrating supplementary prompts. Our approach utilizes pre-trained modules of a Variational autoencoder (VAE) and a modified U-shaped network (UNet) to enable robust semantic encoding, decoding, and effective channel denoising. This scheme significantly enhances the system's ability to preserve data integrity and meaning in noisy environments. By introducing additional context-aware prompts during transmission, we improve the accuracy of received information and mitigate the adverse effects of interference and noise. Extensive simulations show that our framework outperforms previous innovative models, demonstrating superior communication fidelity and efficiency under various challenging conditions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
