Hardware architecture for list successive cancellation polar decoder

2014 IEEE International Symposium on Circuits and Systems (ISCAS), 2014
This 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, 2020
Polar 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), 2020
This 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), 2019
Achieving 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), 2016
As 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.

Efficient adaptive list successive cancellation decoder for polar codes

2014 48th Asilomar Conference on Signals, Systems and Computers, 2014
By 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 ...

An Efficient List Successive Cancellation Decoder for Polar Codes

JSTS:Journal of Semiconductor Technology and Science, 2016
Polar codes are one of the most favorable capacity-achieving codes due to their simple structure and low decoding complexity. However, because of the disappointing decoding performance realized using conventional successive cancellation (SC) decoders, polar codes cannot be used directly in practical applications. In contrast to conventional SC decoders,

Efficient stochastic list successive cancellation decoder for polar codes

2015 28th IEEE International System-on-Chip Conference (SOCC), 2015
Representing continuous values by streams of random binary bits, stochastic decoding has shown advantages in both hardware efficiency and fault tolerance, therefore has been widely adopted by iterative decoding of error correction codes such as low-density parity-check (LDPC) codes and so on.

Fast Multibit Decision Polar Decoder for Successive-Cancellation List Decoding

Journal of Signal Processing Systems, 2020
Successive-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 ...

Low-Complexity List Successive-Cancellation Decoding of Polar Codes Using List Pruning

2016 IEEE Global Communications Conference (GLOBECOM), 2016
The performance of List Successive-Cancellation Decoding (LSCD) of Polar Codes with large list size have exceeded that of Turbo codes and Low-Density Parity-Check codes. However, large list size results in huge computation complexity and this limits the applicability of LSCD in high-throughput and power- sensitive applications.
