LDPC LDPC LDPC ENCODER AND LDPC ENCODING METHOD

摘要

The present invention provide a low-density parity-check (LDPC) encoding method of a computing device. According to the present invention, the computing device LDPC encodes information with a parity check matrix with R rows and (C + R) columns which define an LDPC code. When the parity check matrix is divided into a first matrix with R rows and C columns and a second matrix with R rows and R columns, each element of the first matrix indicates the number of times of permutation of a unit matrix with Z rows and Z columns. A first row of the first matrix has all the elements 0, and an r^th row of the first matrix has a unit value starting from 1 and incremented by (r-1) units, and modular Z calculated values are arranged as elements. Here, R, C, and Z are natural numbers, and r is an integer of 2 to R.
