List successive cancellation decoding of polar codes
Electronics Letters, 2012 A list successive cancellation (LSC) decoding algorithm to boost the performance of polar codes is proposed. Compared with traditional successive cancellation decoding algorithms, LSC simultaneously produces at most L locally best candidates during the decoding process to reduce the chance of missing the correct codeword.

Dual Coupled Polar Codes with Successive Cancellation List Decoding
2021 IEEE International Symposium on Information Theory (ISIT), 2021In this paper, we propose a new coding scheme called dual coupled polar (DC-polar) code, which is constructed by coupling two basic polar codes. We present a successive cancellation list (SCL) decoding algorithm, where a list of candidates are generated from the first basic polar code and the most likely one is identified by combining the second basic ...

Hardware Architecture for List Successive Cancellation Decoding of Polar Codes [PDF]
IEEE Transactions on Circuits and Systems II: Express Briefs, 2014 This brief presents a hardware architecture and algorithmic improvements for list successive cancellation (SC) decoding of polar codes. More specifically, we show how to completely avoid copying of the likelihoods, which is algorithmically the most cumbersome part of list SC decoding.

Enhanced Successive Cancellation List Decoding of Polar Codes
IEEE Communications Letters, 2017Polar 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

An Efficient Successive Cancellation List Decoder for Polar Codes
2019 IEEE International Conference on Communications Workshops (ICC Workshops), 2019Achieving 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 ...

Hardware architecture for list successive cancellation polar decoder
2014 IEEE International Symposium on Circuits and Systems (ISCAS), 2014This 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.

Simplified Metric Sorting for Multi-Bit Successive Cancellation List Decoding of Polar Codes
IEEE Communications Letters, 2023This letter focuses on the metric sorting step for multi-bit successive cancellation list (SCL) decoders of polar codes, which is an important part of the whole decoder. We propose a primary-secondary exchange sorting (PSES) method.

List Estimation-aided Successive-Cancellation List Decoding of Polar Codes
2018 IEEE/CIC International Conference on Communications in China (ICCC), 2018List 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.
