Successive Cancellation Automorphism List Decoding of Polar Codes
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 ...

A Low-latency Successive Cancellation List Decoding Algorithm for Polar Codes [PDF]
Jisuanji gongcheng, 2018 In order to further reduce the decoding delay,a low-latency adaptive Successive Cancellation List(SCL) decoding algorithm based on path reuse is proposed.A repeated path replicating scheme based on CRC check is adopted for the phenomenon that there is a ...

A Complexity Reduction Method for Successive Cancellation List Decoding [PDF]
IEEE Transactions on Circuits and Systems II: Express Briefs, 2020 This brief introduces a hardware complexity reduction method for successive cancellation list (SCL) decoders. Specifically, we propose to use a sorting scheme so that L paths with smallest path metrics are also sorted according to their path indexes for path pruning.

Interleaved Local Sorting for Successive Cancellation List Decoding of Polar Codes
IEEE Access, 2021 In the successive cancellation list decoding of polar codes, the metric sorting dominates the overall decoding latency. To reduce the latency of metric sorting, this paper proposes a new sorting method, called interleaved local sorting, which divides the

An Area-Efficient Hybrid Polar Decoder With Pipelined Architecture
IEEE Access, 2020 As the first kind of capacity-achieving forward error correction (FEC) codes, polar codes have attracted much research interest recently. Compared with traditional FEC codes, polar codes show better error correction performance when successive ...

Successive Cancellation Priority Decoding of Polar Codes
IEEE Access, 2019 The successive cancellation list (SCL) decoding of polar codes can achieve a performance close to that of maximum-likelihood decoding. Nevertheless, a large list size results in high-computational complexity.

Large-Small Sorting for Successive Cancellation List Decoding of Polar Codes
IEEE Access, 2020 The successive cancellation list (SCL) decoding is used to achieve good error-correcting performance for practical finite-length polar codes. However, the metric sorting that is repeatedly performed in SCL decoding increases the overall decoding latency ...

Joint Successive Cancellation List Decoding for the Double Polar Codes
IEEE Communications Letters, 2022 As a new joint source-channel coding scheme, the double polar (D-Polar) codes have been proposed recently. In this letter, a novel joint source-channel decoder, namely the joint successive cancellation list (J-SCL) decoder, is proposed to improve the decoding performance of the D-Polar codes.

Segmented Successive Cancellation List Polar Decoding with Tailored CRC [PDF]
Journal of Signal Processing Systems, 2019 As the first error correction codes provably achieving the symmetric capacity of binary-input discrete memory-less channels (B-DMCs), polar codes have been recently chosen by 3GPP for eMBB control channel. Among existing algorithms, CRC-aided successive cancellation list (CA-SCL) decoding is favorable due to its good performance, where CRC is placed at
