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 ...

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.

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

Simplified Successive-Cancellation List decoding of polar codes
2016 IEEE International Symposium on Information Theory (ISIT), 2016The 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

Design of Successive cancellation List Decoding of Polar Codes
2021 6th International Conference on Communication and Electronics Systems (ICCES), 2021Due 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.

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.

Efficient stochastic successive cancellation list decoder for polar codes
Science China Information Sciences, 2020Polar 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.

Partitioned Adaptive Successive-Cancellation List Decoder for Polar Codes
2020 IEEE 20th International Conference on Communication Technology (ICCT), 2020This paper focuses on a generalization of the well-known adaptive successive cancellation list decoding decoding (ASCLD) of polar codes, characterized by several extra decoding attempts with larger list size, when all the previous decoding attempts fail.

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 ...

Efficient adaptive successive cancellation list decoders for polar codes
2016 IEEE International Conference on Digital Signal Processing (DSP), 2016As 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.
