Bidirectional stack decoding of polar codes [PDF]

open access: yesVojnotehnički Glasnik, 2021
Introduction/purpose: The paper introduces a reduced latency stack decoding algorithm of polar codes, inspired by the bidirectional stack decoding of convolutional codes and based on the folding technique.

Polar Coding for Processes With Memory [PDF]

open access: yesIEEE Transactions on Information Theory, 2016
We study polar coding for stochastic processes with memory. For example, a process may be defined by the joint distribution of the input and output of a channel. The memory may be present in the channel, the input, or both. We show that $ψ$-mixing processes polarize under the standard Arıkan transform, under a mild condition.

A Modified Approach to Punctured Product Polar Codes

open access: yesJournal of Telecommunications and Information Technology, 2019
A high-performance polar code introduced as a product polar code can be constructed by concatenating two short length polar codes. The punctured structure of this code was achieved by puncturing one of its constituent codes.

A novel method for encoding and decoding based on enhanced parity-check-concatenated polar codes

open access: yesDianxin kexue, 2021
Polar codes have perfect coding and decoding performance as a kind of error correction code, which have become a standard coding scheme for 5G short code control channel. While the length of polar codes is short, its performance is not good enough.

Compound polar codes

open access: yes2013 Information Theory and Applications Workshop (ITA), 2013
A capacity-achieving scheme based on polar codes is proposed for reliable communication over multi-channels which can be directly applied to bit-interleaved coded modulation schemes. We start by reviewing the ground-breaking work of polar codes and then discuss our proposed scheme.

Polar-Coded Modulation

open access: yesIEEE Transactions on Communications, 2013
A framework is proposed that allows for a joint description and optimization of both binary polar coding and $2^m$-ary digital pulse-amplitude modulation (PAM) schemes such as multilevel coding (MLC) and bit-interleaved coded modulation (BICM). The conceptual equivalence of polar coding and multilevel coding is pointed out in detail.

On the Concatenations of Polar Codes and Non-Binary LDPC Codes

open access: yesIEEE Access, 2018
An interleaved concatenation scheme of polar codes with non-binary low-density parity check (NBLDPC) codes is proposed in this paper to improve the error-correcting performance of polar codes with finite code length. The information blocks of inner polar

Systematic Polar Coding [PDF]

open access: yesIEEE Communications Letters, 2011
Polar codes were originally introduced as a class of non-systematic linear block codes. This paper gives encoding and decoding methods for systematic polar coding that preserve the low-complexity nature of non-systematic polar coding while guaranteeing the same frame error rate.

High Performance Short Polar Codes: A Concatenation Scheme Using Spinal Codes as the Outer Code

open access: yesIEEE Access, 2018
An innovative scheme for concatenating the polar codes with the recently proposed spinal codes is presented in this paper. The primary objective is to improve the performance of the polar codes in the finite-length regime.
