Hybrid BP-SC/SCF Decoding for Polar Codes
2021 IEEE International Conference on Consumer Electronics-Taiwan (ICCE-TW), 2021There are two main algorithms, successive cancellation (SC) algorithm and brief propagation (BP) algorithm, for decoding polar code. The SC algorithm has better error-correcting performance and the BP algorithm has low latency. The hybrid BP-SC decoding combines these two decoding algorithms and achieves improvements.

On Decoding Random-Access SC-LDPC Codes
2019 IEEE International Symposium on Information Theory (ISIT), 2019We study a new decoding strategy of multi-block SC-LDPC codes motivated by data-storage applications. To decode a sub-block out of the full code block, our proposed decoder accesses a small number of sub-blocks around the desired sub-block. We call this decoding strategy "semi-global decoding", and parametrize it by its access cost: the number of ...

Efficient Folded SC Polar Line Decoder
2018 IEEE 23rd International Conference on Digital Signal Processing (DSP), 2018This paper aims at designing a hardware efficient architecture for successive cancellation (SC) polar decoder. Existing literatures have shown that SC polar decoder can be implemented with $\mathcal{O}(M)$ processing elements and $\mathcal{O}(M)$ memory elements, where $M$ is the code length.

Fast SC-Flip Decoding of Polar Codes with Reinforcement Learning
ICC 2021 - IEEE International Conference on Communications, 2021In this paper, we introduce a novel bit-flipping algorithm for fast successive cancellation (FSC) decoding of polar codes. In particular, we first propose a new bit-flipping strategy tailored to single parity-check (SPC) constituent codes of polar codes.

An Adjustable Hybrid SC-BP Polar Decoder
2018 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2018Polar codes have drawn lots of attentions for the capacity-achieving property and low encoding/decoding complexity. As two promising decoding algorithms, successive cancellation (SC) decoding shows better performance but limited by high latency. Otherwise, belief Propagation (BP) algorithm presents high throughput yet with performance degradation.

A New Reduced-Latency SC Decoder for Polar Codes
2015 International Conference on Intelligent Information Hiding and Multimedia Signal Processing (IIH-MSP), 2015Thanks to the property of provably capacity-achieving, the recently-discovered polar codes have been taken many attentions. However, the required long code length makes the decoding latency of the successive cancellation (SC) decoder high. This paper presents a new pre-computation look-ahead technique to reduce the decoding latency of SC.

Simulated Annealing Algorithm-Aided SC Decoder for Polar Codes
Journal of Circuits, Systems and Computers, 2022A new decoding scheme aided by simulated annealing algorithm is proposed to further improve the decoding performance of successive cancellation (SC) for polar codes at the short block. We use simulated annealing to revise the decoding result of SC which cannot pass the CRC check. To generate the new neighbors, the decoder flips one bit from the set of

Segmented CRC-Aided SC List Polar Decoding
2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016Because of the existence of channel noise, channel coding serves as an indispensable part of mobile communication system and the essential guarantee for the reliable, accurate, and effective transmission of information. As one of the most competitive channel code candidates for the 5th generation (5G) mobile communication, polar codes are the first ...

Efficient SC Decoding of Convolutional Polar Codes
2018 International Symposium on Information Theory and Its Applications (ISITA), 2018An efficient numerically stable successive cancellation decoding algorithm for convolutional polar codes is proposed. The proposed algorithm makes use of only summation and comparison operations, and admits immediate extension to the case of list SC decoding, which provides near-ML performance.

Model-based Design of Hardware SC Polar Decoders for FPGAs
ACM Transactions on Reconfigurable Technology and Systems, 2020Polar codes are a new error correction code family that should be benchmarked and evaluated in comparison to LDPC and turbo-codes. Indeed, recent advances in the 5G digital communication standard recommended the use of polar codes in EMBB control channels.
