Abstract:
1. A multi-carrier transmission apparatus comprising: i) a first amplitude suppression unit suppressing amplitude of an oversampled multi-carrier signal; ii) a first Fourier transform unit transforming an output signal of said first amplitude suppression unit into a frequency domain; iii) a first signal suppression unit suppressing a signal outside a band of an output signal from said first Fourier transform unit under a predetermined condition; iv) a first inverse Fourier transform unit receiving a multi-carrier signal with respect to a signal within the band, receiving an output signal from said first signal suppression unit with respect to a signal outside the band, and inverse Fourier transforming these received signals; v) a second amplitude suppression unit suppressing amplitude of an output signal from said first inverse Fourier transform unit; vi) a second Fourier transform unit transforming an output signal of said second amplitude suppression unit into a frequency domain; vii) a second signal suppression unit suppressing a signal outside a band of an output signal from said second Fourier transform unit under a predetermined condition; and viii) a second inverse Fourier transform unit receiving the multi-carrier signal with respect to the signal within the band, receiving an output signal from said second signal suppression unit with respect to a signal outside the band, and inverse Fourier transforming these received signals.
