Abstract: An LDPC encoding method of a computing device is provided. The computing device performs LDCP encoding on information with a parity check matrix with R rows and (C+R) columns defining an LDPC code. When the parity check matrix is divided into a first matrix with R rows and R columns and a second matrix with R rows and R columns, each element of the first matrix indicates a number of times an identity matrix with Z rows and Z columns are circularly shifted. All elements in the first row of the first matrix are 0. In the r-th row of the first matrix, elements obtained by performing a modulo Z operation (mod Z) on values which are sequentially incremented by (r−1) starting from 0 are arranged. R, C, and Z are natural numbers, and r is an integer from 2 to R.

Abstract: Disclosed herein is a method and apparatus for transferring extrinsic information of a turbo decoder. In the method of transferring the extrinsic information of the turbo decoder according to the present invention, Log-Likelihood Ratio (LLR) values for input bits of the turbo decoder are calculated. The LLR values are transferred as extrinsic information values.
