DESIGN OF ROBUST AND UNIVERSAL POLAR CODES

Title:

DESIGN OF ROBUST AND UNIVERSAL POLAR CODES

Document Type and Number:

WIPO Patent Application WO/2018/136430

Kind Code:

A3

Abstract:

Aspects of the disclosure relate to polar coding. A polar codeword may be generated by sorting a plurality of synthetic channels utilized for transmission of the polar codeword over an air interface in order of reliability utilizing a convex combination of the mutual information calculated for each synthetic channel based on an Additive White Gaussian Noise (AWGN) channel and the mutual information calculated for each synthetic channel based on a binary erasure channel. A polar codeword may further be generated by sorting the plurality of synthetic channels in order of reliability utilizing cumulative sums calculated for each synthetic channel. Each cumulative sum may be calculated from a binary representation of a position of the synthetic channel within the plurality of synthetic channels.
