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.TurkishApproximation methodsComputational resourcesNon-binaryPolar codesSource alphabetApproximation theorySignal processingConvolutional codesConference Paper10.1109/SIU.2012.6204702
