    Abstract: PURPOSE: An apparatus and a method for transmitting/receiving data in a communication system are provided to receive a complex signal of broadcasting data by using a vestigial sideband/single side band modulation system. CONSTITUTION: A serial/parallel conversion part(110) changes data into an I signal and a Q signal. Multiplicators(115,120) multiply orthogonal sequence and transformed I signal and Q signal. Transform units(130,135) hilbert-transform the I signal and Q signal. Combiners(140,145) add the hilbert-transformed I signal and Q signal to the I signal and Q signal. An intermediate frequency/radio frequency part(150) transmits an up-conversed signal.

    Abstract: PURPOSE: An apparatus and a method for transmitting data in a communication system are provided to transmit a large amount of data without performance degradation in a low coding rate. CONSTITUTION: A first repeater(110) repeats the information bit of data to be transmitted first repeat times. An interleaver(120) interleaves the information bit repeated first repeat times. An accumulator(130) accumulatively encodes the interleaved information bit. A second repeater(140) repeats the accumulatively encoded information bit secondary repeat times. A punching machine(150) punches the information bit repeated secondary repeat times. A parallel-serial converter(160) outputs the encoded information bit.
