Abstract

The embodiment of the invention discloses a method used for processing a polarization code and a communication device. The method comprises the steps of obtaining a first serial number set of M uncoded bits corresponding to the number M of target coded bits based on preset first mapping relationship information and the number M of the target coded bits, wherein the first mapping relationship information is used for indicating a one-to-one correspondence relationship between the number of the multiple coded bits and the serial number set of the multiple uncoded bits, the M uncoded bits comprise K information bits, and the M target coded bits are obtained after the M uncoded bits are subjected to polarization coding; and selecting K serial numbers from the first serial number set of the M uncoded bits according to a preset first selecting rule to serve as a serial number set of the K information bits. In the embodiment, the corresponding relationship between the length 2n of the coded bits and the serial number set of the uncoded bits can only be included, so the storage space is greatly reduced, and the coding and decoding efficiency of the polarization code is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and communication equipment for processing polar codes. Background technique [0002] Communication systems usually use channel coding to improve the reliability of data transmission and ensure the quality of communication. Polar codes are encoding methods that can obtain Shannon capacity and have low encoding and decoding complexity. Polar codes are a type of linear block codes. Its generating matrix is ​​G N. , whose encoding process is in, is a binary row vector, Code length N=2 n , n≥0. [0003] B N is an N×N transposition matrix, such as a bit reversal matrix. is F 2 The Kronecker power of , defined as [0004] During the encoding process of Polar code, A part of the bits is used to carry information, called information bits, and the set of the serial numbers of these information bits is denoted as A; the other part of the bits is set to a fixe...
