Polar Codes based on Bit Flipping Improved BP Decoding Algorithm

open access: yesGuangtongxin 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

open access: yesIEEE 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 ...

Error performance analysis of the symbol-decision SC polar decoder [PDF]

open access: yes2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016
Polar codes are the first provably capacity-achieving forward error correction codes. To improve decoder throughput, the symbol-decision SC algorithm makes hard-decision for multiple bits at a time. In this paper, we prove that for polar codes, the symbol-decision SC algorithm is better than the bit-decision SC algorithm in terms of the frame error ...

Complexity‐adjustable SC decoding of polar codes for energy consumption reduction [PDF]

open access: yesIET Communications, 2019
This study proposes an enhanced list‐aided successive cancellation stack (ELSCS) decoding algorithm with adjustable decoding complexity. Also, a logarithmic likelihood ratio‐threshold based path extension scheme is designed to further reduce the memory consumption of stack decoding.

Simplified polar code decoding algorithm

open access: yesDianzi 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 ...

Successive Cancellation Decoding With Future Constraints for Polar Codes Over the Binary Erasure Channel

open access: yesIEEE Access, 2023
In the conventional successive cancellation (SC) decoder for polar codes, all the future bits to be estimated later are treated as random variables. However, polar codes inevitably involve frozen bits, and their concatenated coding schemes also include ...

Analysis of Spatially-Coupled Counter Braids [PDF]

open access: yes, 2015
A counter braid (CB) is a novel counter architecture introduced by Lu et al. in 2007 for per-flow measurements on high-speed links. CBs achieve an asymptotic compression rate (under optimal decoding) that matches the entropy lower bound of the flow size ...

Progressive Bit-Flipping Decoding of Polar Codes: A Critical-Set Based Tree Search Approach

open access: yesIEEE 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

open access: yesIEEE 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 ...

Integer programming‐based non‐uniform window decoding schedules for spatially coupled low‐density parity‐check codes

open access: yesIET Communications, 2022
Spatially coupled low‐density parity‐check (SC‐LDPC) codes generally use a window decoding scheme, which is known to yield a near‐optimal decoding, compared to full block decoding.
