Threshold-Based Fast Successive-Cancellation Decoding of Polar Codes [PDF]
, 2020 Fast SC decoding overcomes the latency caused by the serial nature of the SC decoding by identifying new nodes in the upper levels of the SC decoding tree and implementing their fast parallel decoders.

Folded successive cancelation decoding of polar codes [PDF]
2014 Australian Communications Theory Workshop (AusCTW), 2014 Polar codes are the first explicit class of codes that are provably capacity-achieving under the successive cancelation (SC) decoding. As a suboptimal decoder, SC has quasi-linear complexity N(1 + log N) in the code length N. In this paper, we propose a new non-binary SC decoder with reduced complexity N/2(1 + log N/2) based on the folding operation ...

An Area-Efficient Hybrid Polar Decoder With Pipelined Architecture
IEEE Access, 2020 As the first kind of capacity-achieving forward error correction (FEC) codes, polar codes have attracted much research interest recently. Compared with traditional FEC codes, polar codes show better error correction performance when successive ...

List successive cancellation decoding of polar codes
Electronics Letters, 2012 A list successive cancellation (LSC) decoding algorithm to boost the performance of polar codes is proposed. Compared with traditional successive cancellation decoding algorithms, LSC simultaneously produces at most L locally best candidates during the decoding process to reduce the chance of missing the correct codeword.

On the Derivation of Optimal Partial Successive Interference Cancellation [PDF]
, 2011 The necessity of accurate channel estimation for Successive and Parallel Interference Cancellation is well known. Iterative channel estimation and channel decoding (for instance by means of the Expectation-Maximization algorithm) is particularly ...

Successive-Cancellation Decoding of Linear Source Code [PDF]
2019 IEEE Information Theory Workshop (ITW), 2019 This paper investigates the error probability of several decoding methods for a source code with decoder side information, where the decoding methods are: 1) symbol-wise maximum a posteriori decoding, 2) successive-cancellation decoding, and 3) stochastic successive-cancellation decoding.

Universal Polar Codes for More Capable and Less Noisy Channels and Sources
, 2014 We prove two results on the universality of polar codes for source coding and channel communication. First, we show that for any polar code built for a source $P_{X,Z}$ there exists a slightly modified polar code - having the same rate, the same encoding
