Bounds on the List Size of Successive Cancellation List Decoding

2020 International Conference on Signal Processing and Communications (SPCOM), 2020
Successive cancellation list decoding of polar codes provides very good performance for short to moderate block lengths. However, the list size required to approach the performance of maximum-likelihood decoding is still not well understood theoretically.

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.

Enhanced Successive Cancellation List Decoding of Polar Codes

IEEE Communications Letters, 2017
Polar codes can be efficiently decoded by the successive cancellation list (SCL) algorithm in which the sorter plays an important role. The sorter, however, is time-consuming. We significantly improve this decoding scheme by developing a new non-sorting direct selection method for the SCL algorithm. In the non-sorting strategy, we design a new selector

Hardware architecture for list successive cancellation polar decoder

2014 IEEE International Symposium on Circuits and Systems (ISCAS), 2014
This paper aims at designing an efficient hardware architecture for list successive cancellation (SC) polar decoder. Previous literatures have shown that, compared to conventional SC decoder, list SC decoder has the ability to approach the performance of maximum likelihood (ML) decoder.

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.

Simplified Successive-Cancellation List decoding of polar codes

2016 IEEE International Symposium on Information Theory (ISIT), 2016
The Successive-Cancellation List (SCL) decoding algorithm is one of the most promising approaches towards practical polar code decoding. It is able to provide a good trade-off between error-correction performance and complexity, tunable through the size of the list. In this paper, we show that in the conventional formulation of SCL, there are redundant

List Estimation-aided Successive-Cancellation List Decoding of Polar Codes

2018 IEEE/CIC International Conference on Communications in China (ICCC), 2018
List size determines the ability of successive-cancellation list (SCL) decoding algorithm assisted by the cyclic redundancy check (CRC) for polar codes. To decode a received codeword correctly with exactly matching a list size, a just right list size is required to be estimated.

An Efficient Successive Cancellation List Decoder for Polar Codes

2019 IEEE International Conference on Communications Workshops (ICC Workshops), 2019
Achieving a high decoding throughput using a successive cancellation list (SCL) decoder for polar codes is difficult due to its sequential decoding architecture. In this work, combining the local sorter from a single parity check (SPC) node with a shift-based path memory, a modified fast simplified successive cancellation list (Fast-SSCL) decoder is ...

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.

Efficient stochastic successive cancellation list decoder for polar codes

Science China Information Sciences, 2020
Polar codes are one of the most favorable capacity-achieving codes owing to their simple structures and low decoding complexity. Successive cancellation list (SCL) decoders with large list sizes achieve performances very close to those of maximum-likelihood (ML) decoders.
