Title:

DECODER, DECODING METHOD, AND COMPUTER STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2020/001212

Kind Code:

A1

Abstract:

Disclosed is a decoder. At least one computing unit of the decoder is configured to: acquire soft bit information to be decoded of a variable node n in a basic matrix; determine whether the number of decoding iterations i is less than a decoding iteration threshold; if yes, determine whether the number of decoding layers k is smaller than the number of rows a of the basic matrix; if it is determined that k is smaller than a, determine the soft bit information of the variable node n in a kth layer according to the soft bit information of the variable node n in a k-1th layer, and determine variable node information in a k+1th layer according to the soft bit information of the variable node n in the k-1th layer; determine check node information in the k+1th layer according to the variable node information in the k+1th layer; update k to k+1, re-determine whether k is smaller than a; if it is determined that k is greater than or equal to a, update i to i+1, and re-determine whether i is smaller than the decoding iteration threshold until i equals to the decoding iteration threshold. Also disclosed are a decoding method and a computer storage medium.
