Improved Soft-aided Error-and-erasure Decoding of Product Codes with Dynamic Reliability Scores

TL;DR

This paper introduces a low-complexity soft-aided decoding method for product codes that uses dynamic reliability scores, achieving significant coding gains over traditional hard-decision decoders.

Contribution

It presents a novel decoding approach combining dynamic reliability scores with error-and-erasure decoding for product codes.

Findings

Coding gains of up to 1.2 dB over hard-decision decoders

Reduced decoding complexity

Effective use of dynamic reliability scores

Abstract

We propose a novel soft-aided low-complexity decoder for product codes based on dynamic reliability scores and error-and-erasure decoding. We observe coding gains of up to 1.2 dB compared to conventional hard-decision decoders.
