New diffusion models GD4 and SGDiT advance MIMO detection performance

Researchers have developed two new diffusion-based methods for Multiple-Input Multiple-Output (MIMO) detection in wireless communications. GD4, a graph-based discrete denoising diffusion approach, operates directly in the discrete symbol space for faster inference and improved performance in under-determined systems. The Soft Graph Diffusion Transformer (SGDiT) reformulates detection as a progressive denoising process, using a transformer architecture and a cross-entropy objective for better alignment with discrete symbol detection.
