Denoising Diffusion Error Correction Codes

Understand

Error correction code (ECC) is an integral part of the physical communication layer, ensuring reliable data transfer over noisy channels.

• Recently, neural decoders have demonstrated their advantage over classical decoding techniques.
• However, recent state-of-the-art neural decoders suffer from high complexity and lack the important iterative scheme characteristic of many legacy decoders.
• In this work, we propose to employ denoising diffusion models for the soft decoding of linear codes at arbitrary block lengths.
