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…

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…

Subcode Ensemble Decoding of Polar Codes
Henning Lulei, Jonathan Mandelbaum, Marvin Rübenacke +3
In the short block length regime, pre-transformed polar codes together with successive cancellation list (SCL) decoding possess excellent error correction capabilities. However, in…
