Efficient Probabilistic Parity Shaping for Irregular Repeat-Accumulate LDPC Codes
Diego Lentner, Thomas Wiegart, Richard D. Wesel
Algorithms are presented that efficiently shape the parity bits of systematic irregular repeat-accumulate (IRA) low-density parity-check (LDPC) codes by following the sequential en…
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…
Probabilistic Shaping for Asymmetric Channels and Low-Density Parity-Check Codes
Thomas Wiegart, Linfang Wang, Diego Lentner +1
An algorithm is proposed to encode low-density parity-check (LDPC) codes into codewords with a non-uniform distribution. This enables power-efficient signalling for asymmetric chan…
Improved List Decoding for Polar-Coded Probabilistic Shaping
Constantin Runge, Thomas Wiegart, Diego Lentner
A modified successive cancellation list (SCL) decoder is proposed for polar-coded probabilistic shaping. The decoder exploits the deterministic encoding rule for shaping bits to ru…
Concatenated Forward Error Correction with KP4 and Single Parity Check Codes
Diego Lentner, Emna Ben Yacoub, Stefano Calabrò +3
Concatenated forward error correction is studied using an outer KP4 Reed-Solomon code with hard-decision decoding and inner single parity check (SPC) codes with Chase/Wagner soft-d…
Multilevel Binary Polar-Coded Modulation Achieving the Capacity of Asymmetric Channels
Constantin Runge, Thomas Wiegart, Diego Lentner +1
A multilevel coded modulation scheme is studied that uses solely binary polar codes and Honda-Yamamoto probabilistic shaping. The scheme is shown to achieve the capacity of discret…
Probabilistic Parity Shaping for Linear Codes
Georg Böcherer, Diego Lentner, Alessandro Cirino +1
Linear layered probabilistic shaping (LLPS) is proposed, an architecture for linear codes to efficiently encode to shaped code words. In the previously proposed probabilistic ampli…
