Abstract:
1. A communication processing system comprising: an OFDM transmitter; and a control station configured to provide a service area including a plurality of OFDM transmitters, wherein, for every OFDM transmitter included in the same service area, the control station determines time symbols of data to which macro diversity reception is applied, and determines at least one of an orthogonal code by which pilot channel signals are multiplied in transmission of the data in every OFDM transmitter included in the same service area and a pilot arrangement of the pilot channel signals; the control station transmits, to all the OFDM transmitters included in the same service area, time symbol information about the determined time symbols, and at least one of the orthogonal code and the pilot arrangement; and each of the OFDM transmitters included in the same service area receives the time symbol information from the control station, receives at least one of the orthogonal code and the pilot arrangement from the control station, performs, on the basis of at least one of the orthogonal code and the pilot arrangement from the control station, at least one of a multiplication using the orthogonal code and an assignment of the pilot channel signals to subcarriers on the basis of the pilot arrangement, sets a subcarrier group, generates an OFDM signal according to time symbols based on the time symbol information, and transmits the generated OFDM signal to an OFDM receiver.
