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.

Successive Cancellation List Decoder with Adaptive List Length
2019 11th International Conference on Wireless Communications and Signal Processing (WCSP), 2019Successive cancellation list decoder, which is generalized from successive cancellation decoder by increasing list size, is an effective decoding algorithm for polar codes. However, the list length is invariant throughout the decoding process which leads to redundant computation.

Joint List Polar Decoder with Successive Cancellation and Sphere Decoding
2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018For polar codes, both successive cancellation list (SCL) decoding and list sphere decoding (LSD) aim to balance performance and complexity. The same list structure but different decoding schedules of SCL and LSD can lead to a combination of both schemes.

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 ...

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 ...

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

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 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 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

Successive Cancellation List Decoding of Product Codes With Reed-Muller Component Codes [PDF]
IEEE Communications Letters, 2019 This letter proposes successive cancellation list (SCL) decoding of product codes with Reed–Muller (RM) component codes. SCL decoding relies on a product code description based on the 2 x2 Hadamard kernel, which enables interpreting the code as an RM ...
