Low-Complexity Soft-Aided Error-and-Erasure Decoding for Generalized Product Codes
Sisi Miao, Laurent Schmalen
The paper introduces the refined dynamic reliability score decoder (RDRSD), a low‑complexity hard‑message‑passing error‑and‑erasure decoder for generalized product codes that achie…
Signal Space-Transformed Expectation Propagation for Symbol Detection in ISI Channels
Jannis Clausius, Luca Schmid, Laurent Schmalen +1
Iterative message passing detection based on expectation propagation (EP) has demonstrated near-optimum performance in many signal processing and communication scenarios. The metho…
Ultra-Low-Rate Information Reconciliation: Repetition Coding or Dedicated Codes?
Erdem Eray Cil, Laurent Schmalen
We compare repetition-based ultra-low-rate information reconciliation with dedicated ultra-low-rate codes for CV-QKD. Repetition coding offers a favorable performance-complexity tr…
Modeling and Mitigation of Equalization-Enhanced Phase Noise
Benedikt Geiger, Fred Buchali, Vahid Aref +1
Equalization-enhanced phase noise (EEPN) emerges as a key performance limitation in high symbol-rate coherent transmission systems. In this paper, we highlight recent advances in m…
Affine Subcode Ensemble Decoding for Degeneracy-Aware Quantum Error Correction
Leo Wursthorn, Jonathan Mandelbaum, Sisi Miao +4
Quantum low-density parity-check codes are promising candidates for low-overhead fault-tolerant quantum computing, but degeneracy is known to impair the convergence of belief-propa…
Improved Chase-Pyndiah Decoding for Product Codes with Scaled Messages
Sisi Miao, Mert Birincioglu, Laurent Schmalen
We propose an enhanced Chase-Pyndiah decoder that scales extrinsic messages based on decoder confidence of the component decoder, achieving a 0.1 dB gain over the original with neg…
