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,

Fast Polar Decoding With Successive Cancellation List Creeper Algorithm
IEEE Access, 2023 Polar codes have emerged as a focal point in the field of error-correcting codes, owing to their remarkable capacity-achieving characteristics and their relevance in various modern communication systems. The basic successive cancellation (SC) approach is

Successive Cancellation List Polar Decoder using Log-likelihood Ratios [PDF]
2014 48th Asilomar Conference on Signals, Systems and Computers, 2014 Successive cancellation list (SCL) decoding algorithm is a powerful method that can help polar codes achieve excellent error-correcting performance. However, the current SCL algorithm and decoders are based on likelihood or log-likelihood forms, which ...

Symbol-Based Successive Cancellation List Decoder for Polar Codes [PDF]
2014 IEEE Workshop on Signal Processing Systems (SiPS), 2014 Polar codes is promising because they can provably achieve the channel capacity while having an explicit construction method. Lots of work have been done for the bit-based decoding algorithm for polar codes.

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 ...

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.

Enhanced Adaptive Successive-Cancellation List Decoder
Journal of Physics: Conference Series, 2020 Abstract Adaptive successive cancellation list decoder (ASCLD) with upsizing scheme as a well-known approach can significantly reduce the average list size of SCL algorithm for polar codes with cyclic redundancy check (CRC). Since it needs to re-decode the whole received bits if no survival path verifies CRC, it dramatically increases ...

Low complexity list successive cancellation decoding of polar codes [PDF]
IET Communications, 2014 The authors propose a low complexity list successive cancellation (LCLSC) decoding algorithm, where the advantages of the successive cancellation (SC) decoding and the list successive cancellation (LSC) decoding are both considered. In the proposed decoding, SC decoding instead of LSC decoding is implemented when all information bits from bad ...

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 ...

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 ...
