Fast Multibit Decision Polar Decoder for Successive-Cancellation List Decoding
Journal of Signal Processing Systems, 2020Successive-cancellation list (SCL) decoding for polar codes has the disadvantage of high latency owing to serial operations. To improve the latency, several algorithms with additional circuits have been proposed, but the area becomes larger. This paper proposes a fast multibit decision method having-high area efficiency based on the SCL decoding ...

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 ...

Multi-Bit Successive Cancellation List Decoding of Polar Codes Using One-Bit Error Boundary
IEEE Communications LettersThis letter proposes an efficient method to reduce path splits in the successive cancellation list (SCL) decoding. We construct the boundary consisting of single-bit and multi-bit nodes that have a low error probability within the SC-decoding tree.

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

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.

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 ...

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

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.

Efficient adaptive list successive cancellation decoder for polar codes
2014 48th Asilomar Conference on Signals, Systems and Computers, 2014By keeping a size-L list of intermediate candidates at each decoding step, list successive cancellation (SC) polar decoder successfully achieves better performance compared to the conventional SC polar decoder. However, the size-L list SC decoder will result in linear increase of hardware complexity, which hinders the efficient implementation and ...

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.
