Decoding Product Codes and Staircase Codes with Iteration-Independent Weighting Coefficients
Andreas Straßhofer
This paper presents an improved FEC decoder design outperforming Chase-Pyndiah decoding of product codes by dB. To achieve this, the decoder does not require iteration-depen…

Precoded Polar Product Decoder Based on Soft-Output SCL Decoding and Maximization of Generalized Mutual Information
Nicolás Alvarez Prado, Andreas Straßhofer
We combine two approaches to optimize the iterative decoding of product codes with precoded polar component codes. On one side, we generate bitwise soft messages based on the codeb…

Soft-Information Post-Processing for Chase-Pyndiah Decoding Based on Generalized Mutual Information
Andreas Straßhofer, Diego Lentner, Gianluigi Liva +1
Chase-Pyndiah decoding is widely used for decoding product codes. However, this method is suboptimal and requires scaling the soft information exchanged during the iterative proces…
