Generalized Schematic Successive Cancellation Decoding for Polar Codes
2021 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2021Recently, generalized polar codes were introduced to provide more code lengths and rates without the need for shortening or puncturing. However, as the size of the kernel matrix increases, computing the Log-Likelihood Ratio (LLR) functions in successive cancellation decoder for these codes becomes mathematically more complicated.

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 ...

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

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.

Selective successive cancellation for decoding MIMO-OFDM transmission
2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004A new iterative receiver based on Selective Successive Cancellation (SSC) is proposed for MIMO-OFDM systems. It improves the traditional successive cancellation (SC) method while having low complexity. The algorithm naturally interlaces the SC demodulation iterations with the decoding iterations.

Block successive cancellation decoding of polarization-based codes
2016 9th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2016Linear codes constructed using a polarization transformation followed by short blocklength sub-codes are proposed. Decoding is realized by the successive cancellation algorithm combined with standard optimal or non-optimal decoding of the sub-codes. List successive cancellation decoding can also be used.

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 ...

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
