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.

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 ...

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 ...

Complexity Reduction of Polar Decoders Using Adaptive Fast-SSC and Fast-SSCL Algorithms [PDF]

EPJ Web of Conferences
In this work, we propose a hybrid decoding approach that dynamically segments the received frame into three subframes based on the distribution of the first decoding errors.

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

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 ...

Simplified polar code decoding algorithm

Dianzi Jishu Yingyong, 2018
Polar code is an error correction coding technique, which can prove from the mathematical point of view to reach Shannon′s limit. However, the traditional decoding algorithm, such as the successive cancellation(SC) and the successive cancellation list ...
