Improved Successive Cancellation Decoding of Polar Codes

open access: yes, 2013
As improved versions of successive cancellation (SC) decoding algorithm, successive cancellation list (SCL) decoding and successive cancellation stack (SCS) decoding are used to improve the finite-length performance of polar codes.

Achieving the Uniform Rate Region of General Multiple Access Channels by Polar Coding [PDF]

open access: yes, 2016
We consider the problem of polar coding for transmission over $m$-user multiple access channels. In the proposed scheme, all users encode their messages using a polar encoder, while a multi-user successive cancellation decoder is deployed at the receiver.

Soft-Output Successive Cancellation List Decoding

open access: yesIEEE Transactions on Information Theory
We introduce an algorithm for approximating the codebook probability that is compatible with all successive cancellation (SC)-based decoding algorithms, including SC list (SCL) decoding. This approximation is based on an auxiliary distribution that mimics the dynamics of decoding algorithms with an SC decoding schedule.

Fast Simplified Successive-Cancellation List Decoding of Polar Codes [PDF]

open access: yes2017 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2017
Polar codes are capacity achieving error correcting codes that can be decoded through the successive-cancellation algorithm. To improve its error-correction performance, a list-based version called successive-cancellation list (SCL) has been proposed in the past, that however substantially increases the number of time-steps in the decoding process.

Belief Propagation Bit-Flip Decoder for Polar Codes

open access: yesIEEE 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.

Rate‐compatible systematic polar codes

open access: yesIET Communications, 2021
Puncturing and shortening are two common ways to achieve rate‐compatible non‐systematic polar codes (NSPCs). Systematic polar codes (SPCs) have been shown to outperform NSPCs with the same encoding and decoding complexity.

A Split-Reduced Successive Cancellation List Decoder for Polar Codes

open access: yes, 2015
This paper focuses on low complexity successive cancellation list (SCL) decoding of polar codes. In particular, using the fact that splitting may be unnecessary when the reliability of decoding the unfrozen bit is sufficiently high, a novel splitting ...

Judgement of error frames using frozen bits and its applications in decoding of polar codes

open access: yesIET 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 ...
