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

IET 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

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 ...

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

IEEE 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 ...

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 ...

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

IET 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.

Belief Propagation Bit-Flip Decoder for Polar Codes

IEEE Access, 2019
The bit-flip method has been successfully applied to the successive cancellation (SC) decoder to improve the block error rate (BLER) performance for polar codes in the finite code length region.
