This is an incremental improvement for error correction in communication systems.
The paper tackled the problem of decoding product codes by enhancing the Chase-Pyndiah decoder with scaled extrinsic messages based on decoder confidence, resulting in a 0.1 dB gain over the original method with negligible complexity increase.
We propose an enhanced Chase-Pyndiah decoder that scales extrinsic messages based on decoder confidence of the component decoder, achieving a 0.1 dB gain over the original with negligible complexity increase.
