초록
A receiving apparatus of a mobile terminal receiving a signal in a synchronous OFDM system under a multi-cell environment, including a demodulation start controller performing frame synchronization and cell search using a received signal and outputting information on a demodulation start point and a to-be-demodulated neighbor cell; a FFT unit converting a time-domain signal into a frequency-domain signal; a scramble code generator generating scramble codes for the to-be-demodulated neighbor cell from the demodulation start controller and the current cell; a correlator multiplying a signal from the FFT unit and scramble codes from the scramble code generator and outputting correlation signals; demodulators provided corresponding to a current cell and a maximum number of neighbor cells to be demodulated, and demodulating the correlation signals; and a decoder decoding signals from the demodulators and restoring original information transmitted from the corresponding cell.
