Chase-like Decoding: Test Pattern Design and Performance Analysis
Tim Janz, Simon Obermüller, Andreas Zunker +1
Chase-like decoding algorithms are a popular choice for soft-input decoding of algebraic codes. In this paper, we evaluate the performance of different test pattern sets using thre…
Towards a Unified Coding Scheme for 6G
Paul Bezner, Erdem Eray Cil, Jannis Clausius +14
The growing demand for higher data rates necessitates continuous innovations in wireless communication systems, particularly with the emergence of 6G. Channel coding plays a crucia…
ORCAS Codes: A Flexible Generalization of Polar Codes with Low-Complexity Decoding
Andreas Zunker, Marvin Rübenacke, Stephan ten Brink
Motivated by the need for channel codes with low-complexity soft-decision decoding algorithms, we consider the recursive Plotkin concatenation of optimal low-rate and high-rate cod…
Nested Symmetric Polar Codes
Marvin Rübenacke, Andreas Zunker, Felix Krieg +1
In this paper, we propose a data-driven algorithm to design rate- and length-flexible polar codes. While the algorithm is very general, a particularly appealing use case is the des…
Long Polar vs. LDPC Codes under Complexity-Constrained Decoding
Felix Krieg, Marvin Rübenacke, Andreas Zunker +1
The prevailing opinion in industry and academia is that polar codes are competitive for short code lengths, but can no longer keep up with low-density parity-check (LDPC) codes as…
Soft-Output from Covered Space Decoding of Product Codes
Tim Janz, Simon Obermüller, Andreas Zunker +1
In this work, we propose a new soft-input soft-output decoder called soft-output from covered space (SOCS) decoder. It estimates the a posteriori reliability based on the space exp…
