Title: CODING APPARATUS FOR POLAR CODES
Abstract:
It is provided a method, comprising generating a first set of one or more check bits based on one or more information bits of a first segment of an information block of K information bits; constructing a code block comprising the K information bits of the information block and the first set of check bits; performing polar encoding of the code block, wherein the first set of check bits are generated without taking into account any of the one or more information bits of a second segment of the information block;; each of the information bits of the first segment is different from each of the information bits of the second segment;; each of the information bits of the first segment is distributed in the code block on less reliable bit positions for the polar encoding than each of the information bits of the second segment.
