Polar code construction for non-binary source alphabets [İki̇li̇k olmayan kaynak alfabeleri̇ i̇çi̇n kutupsal kod i̇nşasi]

Abstract

In this paper, approximation methods for binary polar code construction proposed by Tal and Vardy are extended to non-binary source alphabets. Additionally, a new approximation method that enables accurate polar code construction with less usage of computational resources is proposed. Efficiency and accuracy of proposed methods are supported analytically and numerically. © 2012 IEEE.
