Abstract

An error correction method and device and a communication system using them, including an LDPC code generation method capable of adjusting an encoding rate of an LDPC code in a variable manner while leaving the length of the code constant by use of an efficient encoding method or mechanism supporting a variable encoding rate, so that the encoding rate of the LDPC code can be adjusted without changing the code length. An error correction method includes a row dividing to divide each of a part or all of rows into two or more rows based on one parity check matrix, and a code construction to construct a plurality of LDPC codes with arbitrary code rates, respectively.
