Efficient adaptive successive cancellation list decoders for polar codes

2016 IEEE International Conference on Digital Signal Processing (DSP), 2016
As improved versions of the successive cancellation (SC) decoder, the adaptive SC list (SCL) decoder and the segmented CRC-aided SCL (SCA-SCL) decoder can achieve notable complexity reduction compared to the traditional SCL one. However, the former only shows good reduction in high SNR region whereas the latter only works good in low SNR region.

Design of Successive cancellation List Decoding of Polar Codes

2021 6th International Conference on Communication and Electronics Systems (ICCES), 2021
Due to the introduction of 5G, the Polar codes have attracted researchers in the communication field. It is one of a linear block error-correcting codes. This is a kind of Information channel coding techniques with low-complexity in nature wherein the encoding and decoding operation will be performed.

Bit-interleaved polar coded modulation with iterative successive cancellation list decoding

China Communications, 2022
This paper introduces bit-interleaved polar coded modulation with iterative detection/decoding (BIPCM-ID). In order to enable the soft output of successive cancellation list (SCL) decoding, two types of re-encoders are proposed, namely the max-re-encoder

An Improved Simplified Successive-Cancellation List Decoding of Polar Codes

2022 IEEE 5th International Conference on Computer and Communication Engineering Technology (CCET), 2022
The Successive-Cancellation List (SCL) algorithm is a popular decoding algorithm for polar codes. Although SCL algorithm overcomes the error propagation problem in polar codes decoding, the improvement of error correction performance needs to pay the ...

Joint List Polar Decoder with Successive Cancellation and Sphere Decoding

2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018
For polar codes, both successive cancellation list (SCL) decoding and list sphere decoding (LSD) aim to balance performance and complexity. The same list structure but different decoding schedules of SCL and LSD can lead to a combination of both schemes.

Deep-Learning-Aided Successive Cancellation List Flip Decoding for Polar Codes

IEEE Transactions on Cognitive Communications and Networking
Polar codes are the first error-correcting code proven to achieve channel capacity based on infinite code length. The Successive Cancellation List Flip (SCLF) decoding algorithm was proposed by flipping an erroneous bit during the next decoding attempt ...

Efficient adaptive list successive cancellation decoder for polar codes

2014 48th Asilomar Conference on Signals, Systems and Computers, 2014
By keeping a size-L list of intermediate candidates at each decoding step, list successive cancellation (SC) polar decoder successfully achieves better performance compared to the conventional SC polar decoder. However, the size-L list SC decoder will result in linear increase of hardware complexity, which hinders the efficient implementation and ...

Adaptive Successive Cancellation List Decoding for Polar-Coded Probabilistic Amplitude Shaping

IEEE Communications Letters
The multi-level coding-based Polar-coded Probabilistic Amplitude Shaping (PAS) involves a pre-coding step for systematic encoding. Due to this, the Cyclic Redundancy Check (CRC) at the receiver is available only post-decoding of all the bit-levels; this ...
