This invention discloses an OFDM receiver that does not require reordering of a sub-carrier and a method for processing an OFDM signal. The OFDM receiver comprises an I/Q demodulator, an FFT processor, a block for correcting fractional frequency errors, a first multiplier, a block for correcting integral frequency errors, a first adder and a second adder. The method for processing an OFDM signal comprises steps of: demodulating a received OFDM signal to an I/Q signal, applying an offset to the I/Q signal, and generating a spectrum signal by quickly Fourier-transforming the I/Q signal to which the offset is applied. |
