| Zusammenfassung: | A frequency range for Fourier transform is controlled and a digital signal is subjected to fast Fourier transform within the controlled range, whereby a plurality of frequency components (FFT signals) in the digital signal are detected. A transmission rate of a received signal is determined using the detected FFT signals and the FFT signals are demodulated by an operation at a speed corresponding to the determined transmission rate. |
