DECODING METHOD FOR EFFICIENT ERROR CORRECTION AND DEVICE THEREOF BY USING CODING METHOD USING THE LDPC

摘要

PURPOSE: A decoding method for efficient error correction and a device thereof are provided to offer a high error correction efficiency and decode the data coded by a coding method using the LDPC(Low Density Parity check Code). CONSTITUTION: Input buffers(110) store the inputted coded signal. A decoder(120) provides a decoded signal by repeatedly decoding the inputted coded signal through an LDPC decoding method. An error correction checker(130) provides a check result by checking the error correction of the decoded signal. A repeated control/decoding time storing part(140) remembers the time saved by succeeding in the error correction and terminating the decoding faster than a predetermined decoding time, and makes the decoder perform the decoding more repeatedly as much as the save time if the decoded signal failing the error correction until a fixed decoding time is generated while decoding the next inputted signal.
