Abstract

According to the invention, the information bit number K of a code block to be coded, the transmission bit number N of the code block to be coded during the transmission process in a real channel, and the rate adaption rule of the code block to be coded are determined, the reliability of each bit in M uncoded bits in the code block to be coded is determined by means of the reliability of each bit in N transmission bits, and therefore K information bits can be determined from the M uncoded bits, and the set A formed by sequence numbers of the information bits is used for the coding or decoding process of a Polar code. Thus, the invention can provide a method for coding or decoding the Polar code on line by means of a communication device.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication, and more specifically, to a method for processing polarized Polar codes and a communication device. 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 othe...
