CONSTITUTION: A channel code bit string includes a first/a second/a third channel code bit strings. The channel code bit string decides a location of a puncturing or a repetition process on the basis of more than one range determined according to a destination code rate of a data string, when a puncturing or a repetition process algorithm is accomplished by one or more than one code symbol unit. The puncturing process for the second and the third channel code bit strings is alternatively carried out by the one or more than one code symbol unit. The second channel code bit string and the third channel code bit string are simultaneously punctured. The second/the third channel code bit strings have same bit indexes in an area corresponding to at least more than one range. The second channel code bit string and the third channel code bit string are alternately punctured.
