Polar codes: Encoding/decoding and rate-compatible jointly design for HARQ system

open access: yesIntelligent and Converged Networks, 2021
Polar coding are the first class of provable capacity-achieving coding techniques for a wide range of channels. With an ideal recursive structure and many elegant mathematical properties, polar codes are inherently implemented with low complexity ...

Polar Codes for Broadcast Channels [PDF]

open access: yesIEEE Transactions on Information Theory, 2013
Polar codes are introduced for discrete memoryless broadcast channels. For $m$-user deterministic broadcast channels, polarization is applied to map uniformly random message bits from $m$ independent messages to one codeword while satisfying broadcast constraints.

Modified pilot selection for channel estimation of systematic polar coded MIMO-OFDM

open access: yesICT Express, 2019
This paper proposes a modified pilot selection for channel estimation of systematic polar coded MIMO-OFDM. Polar codes provably achieve the theoretical limit for communication systems and systematic polar codes generate the codeword that has the same ...

List Decoding of Arıkan’s PAC Codes

open access: yesEntropy, 2021
Polar coding gives rise to the first explicit family of codes that provably achieve capacity with efficient encoding and decoding for a wide range of channels. However, its performance at short blocklengths under standard successive cancellation decoding

Polar-Coded Transmission over 7.8-km Terrestrial Free-Space Optical Links

open access: yesPhotonics, 2023
Free-space optical (FSO) communications can offer high-capacity transmission owing to the properties of the laser beams. However, performance degradation caused by atmospheric turbulence is an urgent issue. Recently, the application of polar codes, which

Polar Codes for Multiple Descriptions [PDF]

open access: yesIEEE Transactions on Information Theory, 2014
A polar coding scheme is proposed for the multiple description coding (MDC) problem and is shown to be able to achieve a certain rate pair on the dominant line of the achievable rate region determined by El Gamal and Cover. This scheme is an adaptation of the one developed by ŗasoglu et al. for the multiple access channel (MAC) to the MDC setting.

On puncturing strategies for polar codes [PDF]

open access: yes2017 IEEE International Conference on Communications Workshops (ICC Workshops), 2017
This paper introduces a class of specific puncturing patterns, called symmetric puncturing patterns, which can be characterized and generated from the rows of the generator matrix $G_N$. They are first shown to be non-equivalent, then a low-complexity method to generate symmetric puncturing patterns is proposed, which performs a search tree algorithm ...

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...
