摘要：A direct conversion receiver includes a down converter for frequency-convertingan analog RF signal modulated by the OFDM method in such a manner that the centerfrequency of the occupied frequency of the reception object segment is frequency zero,AD conversion means for converting a down convert signal obtained by the downconverter into a digital signal, FFT means for performing fast Fourier transform to thesignal obtained by the AD conversion means and converting the time axis into a frequencyaxis, and unnecessary component removal means for removing unnecessary componentsother than the reception object segment from the output signal of the FFT means.
