Title:
DECODING METHOD AND DEVICE, AND DECODER
Document Type and Number:
WIPO Patent Application WO/2019/056941
Kind Code:
A1
Abstract:
A method and device for decoding channel coding in a wireless communication system, and a decoder. The method comprises: determining an information bit set according to information bit quantity K and a target code length N of information to be decoded (S101), and determining a key set according to the information bit set, K and N, wherein the probability that the key set comprises a decoding first error position bit is greater than a first threshold value, and the key set is a subset of the information bit set (S102). According to the key set and a preset rule, polarization decoding is carried out on the information to be decoded, the preset rule being as follows: performing decoding path splitting on information bits in the key set, performing bit-by-bit determination for information bits outside of the key set, generating a decoding path, selecting L paths having the largest PM values when the total number of decoding paths exceeds a preset path width L, saving the same and continuously developing decoding paths, and obtaining a decoding result of each level of decoding bits according to the decoding path of each level of decoding bits (S103). Thus, computing complexity and decoding time delays, which are caused by sequencing, are reduced.
