Scalable Polar Code Construction for Successive Cancellation List Decoding: A Graph Neural Network-Based Approach [PDF]
IEEE Transactions on Communications, 2022 While constructing polar codes for successive-cancellation decoding can be implemented efficiently by sorting the bit channels, finding optimal polar codes for cyclic-redundancy-check-aided successive-cancellation list (CA-SCL) decoding in an efficient ...

Annual Conference on Information Sciences and Systems, 2023 In this work we introduce a framework to study the trade-off between the undetected error rate (UER) and overall frame error rate (FER) of CRC-concatenated polar codes in the short blocklength regime.

Efficient Sorting Architecture for List-Fast-SSC Decoding of Polar Codes
IEEE Access, 2018 Polar codes have been proven to achieve the symmetric capacity of memoryless channel. Compared with a successive cancellation list decoder, list-Fast simplified-successive cancellation generates more candidate paths, which leads to more resource costs ...

An Information-Theoretic Perspective on Successive Cancellation List Decoding and Polar Code Design [PDF]
IEEE Transactions on Information Theory, 2021 This work identifies information-theoretic quantities that are closely related to the required list size on average for successive cancellation list (SCL) decoding to implement maximum-likelihood decoding over general binary memoryless symmetric (BMS ...

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 ...

A Low-Complexity Sorting Network for a Fast List Polar Decoder
IEEE Access, 2023 Fast list decoding algorithms for polar codes have been proposed to achieve low latency and high error correction performance. In the Rate-1 and SPC nodes of fast list decoding, a high-complexity sorter is required if multiple bits are to be decoded ...

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 ...

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 ...

List Decoding of Arıkan’s PAC Codes
Entropy, 2021 Polar coding gives rise to the first explicit family of codes that provably achieve capacity with efficient encoding and decoding for a wide range of channels. However, its performance at short blocklengths under standard successive cancellation decoding
