摘要：
The invention relates to a method and apparatus for a channel decoding using a Low-Density Parity-Check (LDPC) code, the method comprising:
demodulating a signal transmitted from a transmitter;
determining position of the punctured parity bits by estimating information about a predetermined order of parity bit sets to be punctured and the number of parity bit sets ; and
decoding data using the positions of the punctured parity bits,
wherein determining position of punctured parity bits comprises,
determining a number of parity bits to be punctured;
determining a number of parity bit sets to be punctured based on the determined number of parity bits to be punctured; and
acquiring a predetermined order of parity bit sets,
wherein the predetermined order of parity bit sets to be punctured is determined as 6, 4, 13,9,18,8,15,20,5,17,2,22,24,7,12,1,16,23,14,0,21,10,19,11,3, when a codeword length is 16200 and an information length is 7200.
