A Semi-Parallel Successive-Cancellation Decoder for Polar Codes
IEEE Transactions on Signal Processing, 2013Polar codes are a recently discovered family of capacity-achieving codes that are seen as a major breakthrough in coding theory. Motivated by the recent rapid progress in the theory of polar codes, we propose a semi-parallel architecture for the implementation of successive cancellation 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

Bounds on the List Size of Successive Cancellation List Decoding
2020 International Conference on Signal Processing and Communications (SPCOM), 2020Successive 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.

Neural Successive Cancellation Flip Decoding of Polar Codes
Journal of Signal Processing Systems, 2020Dynamic successive cancellation flip (DSCF) decoding of polar codes is a powerful algorithm that can achieve the error correction performance of successive cancellation list (SCL) decoding, with an average complexity that is close to that of successive cancellation (SC) decoding at practical signal-to-noise ratio (SNR) regimes.

On uniform quantization for successive cancellation decoder of polar codes
2014 IEEE 25th Annual International Symposium on Personal, Indoor, and Mobile Radio Communication (PIMRC), 2014Polar codes have a regular-recursive structure, which can efficiently be mapped to hardware for practical applications. A good quantization scheme plays a great important role in hardware implementation. In this paper, three uniform quantizers are designed for successive cancellation (SC) decoding of polar codes based on either optimizing the ...

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.

Effectively Partitioned Implementation for Successive-Cancellation Polar Decoder
2019 IEEE 62nd International Midwest Symposium on Circuits and Systems (MWSCAS), 2019This paper proposes an effective field-programmable gate array (FPGA) implementation of a successive-cancellation (SC) decoder for polar codes that have recently attracted attention as error-correcting codes adopted for 5G wireless systems. We focus on effective ways of partitioning the SC decoding procedure into combinational and sequential logic ...

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 ...

Multiple candidates successive-cancellation decoding of polar codes
2012 International Conference on Wireless Communications and Signal Processing (WCSP), 2012This paper proposes an effective scheme to improve the error performance of conventional successive-cancellation (SC) decoding algorithm for polar codes. The proposed scheme, which is referred to as the multiple candidates (MC) scheme constructs a set of candidates for the starting vector for SC decoding.
