| Abstract(in English) | A major disadvantage of multi-carrier transmission (MCT) is increase of peak power. In this paper, we propose a peak power suppression scheme for MCT system based on generating peak power suppressing signals at extra carrier (parity carrier). This scheme has an advantage that it can be applied to any MCT system and the suppressing signal can be easily spilt at the demodulator. In the case of 8 subcarriers, peak power can be reduced by about 5dB by the proposed scheme. When nonlinearity of the power amplifier is small, out-of-band radiation is decreased to -50dB below the in-band power spectral density with this scheme |
