Channel coding method and apparatus for low density parity check code communication system

The present invention provides a method of using low density parity check (LDPC) code channel coding method. The method comprising: determining a number of parity bits for puncturing; from a predetermined set of parity bits divide the interval formed parity bits; based on the number of parity bits for puncturing, and determining a set of parity bits number; and based on the number of parity to the punctured bits is determined, and according to the predetermined sequence of parity bits is punctured, the punctured parity bits, wherein when a codeword length is 16200 and an information length of 7200, the sequence to be punctured parity bits is determined as set 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.
