On Decoding Random-Access SC-LDPC Codes

2019 IEEE International Symposium on Information Theory (ISIT), 2019
We 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 ...

Segmented CRC-Aided SC List Polar Decoding

2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016
Because 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 ...

An Adjustable Hybrid SC-BP Polar Decoder

2018 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2018
Polar 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.

Simulated Annealing Algorithm-Aided SC Decoder for Polar Codes

Journal of Circuits, Systems and Computers, 2022
A 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

Neural Network Aided SC Decoder for Polar Codes

2018 IEEE 4th International Conference on Computer and Communications (ICCC), 2018
Theoretically, conventional decoders for polar codes can be entirely replaced by neural network (NN) with enough size and enough training, which called NN decoder. But the exponentially increasing training complexity becomes unacceptable when information length increases, which means only decoders for short codes can be trained practically.

Efficient SC Decoding of Convolutional Polar Codes

2018 International Symposium on Information Theory and Its Applications (ISITA), 2018
An 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.

Fast SC-Flip Decoding of Polar Codes with Reinforcement Learning

ICC 2021 - IEEE International Conference on Communications, 2021
In 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.

Parity Check Aided SC-Flip Decoding Algorithms for Polar Codes

IEEE Transactions on Vehicular Technology, 2021
When polar codes are decoded by the successive cancellation (SC) decoding algorithm, erroneously decoded non-frozen bits are caused by either channel noise or error propagation. SC-Flip algorithms aim to improve error performance by first identifying erroneous hard decisions due to channel noise and then flipping them during the decoding process to ...

A New Reduced-Latency SC Decoder for Polar Codes

2015 International Conference on Intelligent Information Hiding and Multimedia Signal Processing (IIH-MSP), 2015
Thanks 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.

Gaussian Approximation Optimized SC- Flip Decoding Algorithm of Polar Codes

2020 IEEE 4th Information Technology, Networking, Electronic and Automation Control Conference (ITNEC), 2020
The polar codes proposed by Arikan is the first channel code proved to achieve the symmetric capacity of any binary input discrete memoryless channel (BDMC). Besides, the polar codes have been chosen for the eMBB control channels in the 5th generation mobile communication system.
