Improved Adaptive Successive Cancellation List Decoding of Polar Codes [PDF]
Entropy (Basel), 2019 Although the adaptive successive cancellation list (AD-SCL) algorithm and the segmented-CRC adaptive successive cancellation list (SCAD-SCL) algorithm based on the cyclic redundancy check (CRC) can greatly reduce the computational complexity of the successive cancellation list (SCL) algorithm, these two algorithms discard the previous decoding result ...

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

Partitioned successive-cancellation list decoding of polar codes [PDF]
2016 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

Successive Cancellation Automorphism List Decoding of Polar Codes [PDF]
2023 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 ...

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

An implementation of list successive cancellation decoder with large list size for polar codes [PDF]
2017 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.

On Path Memory in List Successive Cancellation Decoder of Polar Codes [PDF]
2018 IEEE International Symposium on Circuits and Systems (ISCAS), 2018 Polar code is a breakthrough in coding theory. Using list successive cancellation decoding with large list size L, polar codes can achieve excellent error correction performance. The L partial decoded vectors are stored in the path memory and updated according to the results of list management.
