Title:
DECODING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/088256
Kind Code:
A1
Abstract:
A decoding method and device. The method comprises: performing first decoding on information to be decoded, and obtaining the number of symbol flips of each variable node in a preset set during the first decoding process, wherein the number of symbol flips is the number of symbol flips during the decoding process of external information of all edges connected to the variable node, and the external information is the information transmitted to a check node by the variable node, or the external information is the information transmitted to the variable node by the check node (S101); if the first decoding fails, selecting j variable nodes in descending order of the number of symbol flips, wherein j is a positive integer (S102); setting log-likelihood ratio (LLR) values corresponding to the selected j variable nodes as preset positive and negative values respectively to generate 2j LLR sequences (S103); and decoding the 2j LLR sequences respectively to obtain a decoding output result (S104). Therefore, the accuracy of variable node selection can be improved, and the decoding performance is thus improved.
