Title:

METHOD AND DEVICE FOR ENCODING POLAR CODE

Document Type and Number:

WIPO Patent Application WO/2019/024555

Kind Code:

A1

Abstract:

The present application relates to the technical field of communications and discloses a method and a device for encoding a Polar code. The method improves the accuracy of reliability calculation and sorting for polarized channels. The method comprises: obtaining a first sequence for encoding K bits to be encoded, the first sequence comprising a number sequence of N polarized channels, the number sequence of N polarized channels being sorted into the first sequence according to the reliability of the N polarized channels, wherein K is a positive integer, N is a mother code length of a Polar code, N is 2 to the power of a positive integer, and K ≤ N; selecting, in order of reliability from high to low, the number sequence of K polarized channels from the first sequence; and placing the bits to be encoded according to the selected number sequence of K polarized channels and performing Polar code encoding on the bits to be encoded.
