Abstract
A communication terminal device includes: a turbo encoder that performs two systems of convolutional encoding with respect to input data and preforms turbo encoding processing with in-block interleave preformed on one of the two systems using an internal interleaver. Rate matching (puncturing) units which puncture an output of the turbo encoder based on a predetermined rate matching algorithm and interleavers, which change the output of the turbo encoder such that a puncturing cycle based on the rate matching algorithm of the rate matching units is changed. Accordingly, turbo code performance is improved.
