Abstract

The invention discloses a polarization decoding method based on subsection CRC and belongs to the technical field of wireless communication channel coding. The subsection CRC (cyclic redundancy check) is utilized to improve an existing list successive elimination polarization decoding algorithm, and subsection polarization code CRC is carried out on an original information sequence at a coding end; and at a decoding end, the whole list successive elimination and decoding process is enabled to be divided into a plurality of subsections, CRC is carried out in each subsection, and unsuccessful decoding is judged according to the CRC check result or screening of ineffective paths is carried out. The subsection CRC and the list successive elimination polarization decoding algorithm are combined, so that time complexity of polarization decoding can be effectively reduced, and especially in the low SNR (signal to noise ratio) region, the time complexity of decoding is reduced obviously.

Description

technical field

[0001] The invention relates to a decoding method, in particular to a polar decoding method based on a segmented CRC check, and belongs to the technical field of wireless communication channel coding. Background technique

[0002] Since the 1980s, the rapid progress of communication technology has brought human society into the information age. The continuous development of wireless mobile communication technology provides a powerful impetus for the process of global informatization. Wireless cellular mobile communication has gone through: first-generation analog communication technology, second-generation digital communication technology, third-generation CDMA broadband communication technology, and has now entered the stage of industrialization and commercialization of 4G systems. While 4G technology is being promoted to industrialization and commercialization, mobile communication after 4G has entered the agenda, and the evolution and development of wirel...
