SECS: A Soft Ensemble-Combining Stage for Low-Latency Decoding
Felix Krieg, Paul Bezner, Stephan ten Brink
Ensemble decoding is a promising technique for ultra-reliable low-latency communication, as it trades hardware parallelism for decoding latency by running M diverse belief propagat…
Row-Boosted Ensemble Belief Propagation for Short LDPC Codes
Paul Bezner, Felix Krieg, Stephan ten Brink
Belief-propagation (BP) decoding of short and moderate-length low-density parity-check (LDPC) codes is limited by finite-length graph effects: a single decoder trajectory can becom…
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…
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…
A Comparative Study of Ensemble Decoding Methods for Short Length LDPC Codes
Felix Krieg, Jannis Clausius, Marvin Geiselhart +1
To alleviate the suboptimal performance of belief propagation (BP) decoding of short low-density parity-check (LDPC) codes, a plethora of improved decoding algorithms has been prop…
