1. A mobile station transmitting data to and receiving data from an external base station at high speed, the mobile station comprising:

  • a mobile station communication controller for processing data including control data to output a predetermined data frame;

    a mobile station source coder for receiving the data frame and performing source coding on it according to a predetermined coding method to output coded data;

    a first modulator for receiving a first carrier having a predetermined frequency and modulating the coded signal from the mobile source coder using the first carrier to generate a first modulated signal;

    a second modulator for receiving a second carrier having a predetermined frequency and performing modulation on the first modulated signal using the second carrier to generate a modulated uplink signal;

    a mobile station interfacer for transmitting the modulated uplink signal to the base station and receiving a modulated downlink signal from the base station;

    a first demodulator for receiving and demodulating the modulated downlink signal received from the base station via the mobile station interfacer and outputting demodulated data; and

    a mobile station source decoder for performing source decoding on the demodulated data from the first demodulator to convert the demodulated data to a baseband signal.
