| 1. An apparatus for receiving data in a frequency division multiple access based communication system, the apparatus comprising:
a Fast Fourier Transform (FFT) unit for receiving signals received during one symbol block period and for performing FFT on
the signals;
an Inverse Fast Fourier Transform (IFFT) unit for performing IFFT on the signals output from the FFT unit, thereby restoring
symbol blocks;
a control information demodulator/decoder for, when the symbol block period comprises a symbol block period in which data
and control information are multiplexed, receiving modulation symbols corresponding to IFFT output indexes from among the
symbol blocks and demodulating and decoding the modulation symbols, thereby outputting control information; and
a data demodulator/decoder for receiving modulation symbols corresponding to the other IFFT output indexes except for indexes
corresponding to the control information from among the symbol blocks by using the control information, demodulating and decoding
the received modulation symbols, and then outputting the data.
