Hardware Architecture for List Successive Cancellation Decoding of Polar Codes [PDF]

open access: yesIEEE Transactions on Circuits and Systems II: Express Briefs, 2014
This brief presents a hardware architecture and algorithmic improvements for list successive cancellation (SC) decoding of polar codes. More specifically, we show how to completely avoid copying of the likelihoods, which is algorithmically the most cumbersome part of list SC decoding.

Partitioned successive-cancellation list decoding of polar codes [PDF]

open access: yes2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016
Successive-cancellation list (SCL) decoding is an algorithm that provides very good error-correction performance for polar codes. However, its hardware implementation requires a large amount of memory, mainly to store intermediate results. In this paper, a partitioned SCL algorithm is proposed to reduce the large memory requirements of the conventional

LLR-Based Successive Cancellation List Decoding of Polar Codes [PDF]

open access: yesIEEE Transactions on Signal Processing, 2014
We show that successive cancellation list decoding can be formulated exclusively using log-likelihood ratios. In addition to numerical stability, the log-likelihood ratio based formulation has useful properties which simplify the sorting step involved in successive cancellation list decoding.

Successive Cancellation Automorphism List Decoding of Polar Codes

open access: yes2023 12th International Symposium on Topics in Coding (ISTC), 2023
The discovery of suitable automorphisms of polar codes gained a lot of attention by applying them in Automorphism Ensemble Decoding (AED) to improve the error-correction performance, especially for short block lengths. This paper introduces Successive Cancellation Automorphism List (SCAL) decoding of polar codes as a novel application of automorphisms ...

An implementation of list successive cancellation decoder with large list size for polar codes [PDF]

open access: yes2017 27th International Conference on Field Programmable Logic and Applications (FPL), 2017
Polar codes are the first class of forward error correction (FEC) codes with a provably capacity-achieving capability. Using list successive cancellation decoding (LSCD) with a large list size, the error correction performance of polar codes exceeds other well-known FEC codes.

A Split-Reduced Successive Cancellation List Decoder for Polar Codes [PDF]

open access: yesIEEE Journal on Selected Areas in Communications, 2016
This paper focuses on low complexity successive cancellation list (SCL) decoding of polar codes. In particular, using the fact that splitting may be unnecessary when the reliability of decoding the unfrozen bit is sufficiently high, a novel splitting rule is proposed.

Higher-Order Belief Propagation Correction Decoder for Polar Codes [PDF]

open access: yesEntropy, 2022
Belief propagation (BP) decoding for polar codes has been extensively studied because of its inherent parallelism. However, its performance remains inferior to that of successive cancellation list decoding (SCL) due to the structure of the decoding graph.
