1. A communication processing system comprising:

  • an OFDM transmitter; and

    one or plural control stations configured to provide the same service area including a plurality of OFDM transmitters which are close or substantially the same in cell size,wherein the one or plural control stations transmit first data, second data, and time symbol information to all the OFDM transmitters included in the same service area, receive transmission power margins from the respective OFDM transmitters included in the same service area, determine a transmission power boost value on the basis of the received transmission power margins, and transmit the determined transmission power boost value to all the OFDM transmitters included in the same service area; and

    each of the OFDM transmitters included in the same service area receives the first data, the second data, and the time symbol information from the one or plural control stations, calculates a transmission power margin in a time symbol cased on the time symbol information from the control station, transmits the calculated transmission power margin to the control station, receives a transmission power boost value from the control station, multiplies a data channel signal corresponding to the first data by the received transmission power boost value, generates, in the time symbol based on the time symbol information, an OFDM signal in which a macro diversity signal corresponding to the first data and a non-macro diversity signal corresponding to the second data are frequency-division-multiplexed, and outputs the generated OFDM signal to an OFDM receiver.
