About this project

GramGuidedURA is a research repository designed to reproduce the results of the SPAWC2026 paper. It implements a semi-blind channel estimation method for Unsourced Random Access (URA) leveraging Gram-guided diffusion. The project utilizes a multiuser 3GPP channel dataset and provides a script, `load_and_eval_dm_dps.py`, to evaluate the model's performance across various SNR ranges and pilot configurations. The implementation is based on the Diffusion_channel_est framework.
