Abstract

The invention discloses a two-dimensional coding trap set error pattern search method, which comprises the following steps of: firstly, setting a received codeword C matrix, and setting a bit elementcorresponding to an error codeword to be 0; searching a first candidate column in the matrix C to obtain a P matrix, searching a first candidate row to obtain a P1 matrix, performing iterative searchto obtain a Pk matrix, generating a matrix PM-1 according to the above steps, traversing all column and row combinations according to the above steps until conditions cannot be met, indicating that the matrix does not have a trap set, and ending the search. According to the two-dimensional coding trap set error pattern searching method provided by the invention, trap set error patterns can be effectively searched and estimated.

Description

technical field [0001] The invention belongs to the technical field of information and communication, and in particular relates to a method for searching error patterns of two-dimensional coding trap sets. Background technique [0002] Driven by the rapid development and widespread application of the Internet of Things technology, accurate and fast data acquisition, transmission and storage processing have become indispensable basic requirements in production and life such as smart agriculture, smart manufacturing, and logistics, and error control coding is a data An effective means of reliable storage and transmission, through data error control coding can correct random or burst errors generated in data transmission and storage. The error correction ability of the traditional one-dimensional coding is related to the minimum Hamming distance of the code space, and its error correction ability is limited under certain coding efficiency constraints. Two-dimensional encoding ...
