CODING METHOD, CODING DEVICE, DECODING METHOD AND DECODING DEVICE FOR LOW DENSITY GENERATOR MATRIX CODE

Abstract

The present invention relates to a method and apparatus for coding a low density generation matrix code, and a method and apparatus for decoding. The coding method includes P code rates of R 0. Construct a low density generation matrix code mother code set using low density generation matrix codes of different code lengths, wherein the low density generation matrix code mother code set is a uniform basis matrix. And K b is the number of rows in the base matrix and n b is the number of columns in the base matrix; Obtain a length L of the intermediate variable based on the relationship between the length K of the information bit sequence to be coded in the low density generation matrix code mother code set and the length L of the intermediate variable; Using the length L of the intermediate variable and the number of rows k b of the base matrix, an expansion factor z k for processing the base matrix is obtained, and the expansion matrix z k is used to correct and expand the matrix to generate the generation matrix G ldgc Acquire; Coding a sequence of information bits to be coded using a matrix G ldgc (1: L, 1: N + LK) consisting of the L rows of the generation matrix and the first N + L-K columns.
