Abstract: A method and apparatus for turbo encoding and method and apparatus for turbo decoding are disclosed, by which encoding and decoding speeds of turbo codes and performance thereof can be enhanced. In performing turbo encoding on inputted information bits by a unit of an information frame including a predetermined number of bits, the present invention includes dividing the information frame into at least two information sub-blocks, encoding each of the at least two information sub-blocks independently, rearranging information bits configuring the information frame by interleaving the information frame, dividing the rearranged information frame into at least two information sub-blocks, and encoding each of the at least two information sub-blocks independently.

Abstract: A channel coding method and device using an RA method and puncturing are provided. In the channel coding method, the input information bits are repeated according to a repetition factor, interleaved, and accumulated. The accumulated bit stream and the information bits are converted to a serial bit stream and punctured according to a puncturing pattern. Thus, a codeword with a required coding rate is generated.
