Summary:A method of performing LDPC(Low-Density Parity-Check codes) decoding using a model matrix is provided to perform a decoding process by using the model matrix having high performance. A method of performing LDPC decoding using a model matrix comprises the following steps of: receiving an LDPC coded signal from a channel; iteratively performing a check node update and a variable node update based on the model matrix in which at least two shift numbers are superposed; determining a decoding value based on result values of the check node update and the variable node update; and performing a check for the determined decoding value. The step of performing the check node update includes the step of performing data processing to reflect an operation result processed through at least one among a plurality of edges formed with a superposition structure to a corresponding variable node memory(2001,2002,2003).
