A Scalable Successive-Cancellation Decoder for Polar Codes [PDF]
IEEE Transactions on Signal Processing, 2014 Polar codes are the first error-correcting codes to provably achieve channel capacity, asymptotically in code length, with an explicit construction. However, under successive-cancellation decoding, polar codes require very long code lengths to compete with existing modern codes.

Folded successive cancelation decoding of polar codes [PDF]
2014 Australian Communications Theory Workshop (AusCTW), 2014 Polar codes are the first explicit class of codes that are provably capacity-achieving under the successive cancelation (SC) decoding. As a suboptimal decoder, SC has quasi-linear complexity N(1 + log N) in the code length N. In this paper, we propose a new non-binary SC decoder with reduced complexity N/2(1 + log N/2) based on the folding operation ...

Neural-Network-Assisted Polar Code Decoding Schemes
Applied Sciences, 2022 The traditional fast successive-cancellation (SC) decoding algorithm can effectively reduce the decoding steps, but the decoding adopts a sub-optimal algorithm, so it cannot improve the bit error performance. In order to improve the bit error performance

Threshold-Based Fast Successive-Cancellation Decoding of Polar Codes [PDF]
, 2020 Fast SC decoding overcomes the latency caused by the serial nature of the SC decoding by identifying new nodes in the upper levels of the SC decoding tree and implementing their fast parallel decoders.

Distributed CRC scheme for low-complexity successive cancellation flip decoding of polar codes
ICT Express, 2022 In this paper, we propose a novel successive cancellation flip (SCF) decoding to reduce the computational complexity compared to the conventional SCF decoding by using distributed CRC bits.

Soft-Output Successive Cancellation Stack Polar Decoder [PDF]
IEEE Transactions on Vehicular Technology, 2021 Polar coding has been ratified for employment in the 3GPP New Radio standard and several soft-decision decoders achieved comparable performance to that of the state-of-the-art successive cancellation list decoder. Aiming for further improving the performance of the soft-decision polar decoders, we propose a soft-output successive cancellation stack ...

Molecular Polar Belief Propagation Decoder and Successive Cancellation Decoder [PDF]
2019 IEEE International Workshop on Signal Processing Systems (SiPS), 2019 By constructing chemical reaction networks (CRNs), this paper proposes a method of synthesizing polar decoder using belief propagation (BP) algorithm and successive cancellation (SC) algorithm, respectively. Theoretical analysis and simulation results have validated the feasibility of the method. Reactions in the proposed design could be experimentally

Successive Cancellation Decoding of Single Parity-Check Product Codes [PDF]
, 2017 We introduce successive cancellation (SC) decoding of product codes (PCs) with single parity-check (SPC) component codes. Recursive formulas are derived, which resemble the SC decoding algorithm of polar codes. We analyze the error probability of SPC-PCs
