PURPOSE: An apparatus for controlling a demultiplexer and a multiplexer for rate matching of a mobile communication system is provided to add the demultiplexer for separating symbol data into information symbols and parity symbols on a rate matching front end, when the information symbol does not have to be punctured while a rate matching is performed in a reverse link transmitter, so as to carry out an optimum rate matching. CONSTITUTION: A turbo encoder(110) inputs an information bit stream to encode the information bit stream, and generates information symbols and first/second parity symbols. The first interleaver(120) interleaves symbols encoded in the turbo encoder(110), and outputs the interleaved symbols. A radio frame segmentation block(130) inputs the interleaved symbols, and outputs the symbols as at least one radio frames having same sizes. A demultiplexer(141) demultiplexes the radio frames, and generates the radio frames as three streams, information symbols, first parity symbols, and second parity symbols. Rate matching blocks(142,143,144) bypass the information symbols, and puncture the first and the second parity symbols according to a rate matching, then output the punctured parity symbols. |
