Judgement of error frames using frozen bits and its applications in decoding of polar codes
IET Communications, 2023 Polar codes have received widespread attention because of their excellent performance. However, although successive cancellation (SC)‐based decoding algorithms have achieved excellent error correction performance, they still encounter large time delays ...

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

Polar Codes based on Bit Flipping Improved BP Decoding Algorithm
Guangtongxin yanjiu, 2021 Polar codes is the only coding scheme in the world that has been proved that the Shannon threshold is reachable. Because of the high time delay caused by the serial characteristic of Successive Cancellation (SC) decoding, the Belief Propagation (BP ...

BER Evaluation Based SCFlip Algorithm for Polar Codes Decoding
IEEE Access, 2020 Successive cancellation (SC) decoding of polar codes may bring about error propagation that needs to be mitigated. In this paper, we present a new SC Flipping (SCFlip) decoder, named bit error rate (BER) evaluation based SCFlip (BER-SCFlip), which can ...

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 ...

Progressive Bit-Flipping Decoding of Polar Codes: A Critical-Set Based Tree Search Approach
IEEE Access, 2018 In successive cancellation (SC) polar decoding, an incorrect estimate of any prior unfrozen bit may bring about severe error propagation in the following decoding, and thus it is desirable to find out and correct an error as early as possible.

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 ...
