| Abstract(in English) | As a solution to reduce peak-to-mean power ratio (PMPR)in Multicarrier transmission system, it has been proposed that entire part of IDFT block in which envelope-peak amplitude (EPA) is detected is decreased by a appropriate constant. However, this technique loses the spectral efficiency for redundancy of time-waveform shaping consequently. In this paper, we propose a peak-power-suppression (PPS) scheme which achieves band-limitation by filtering the individual sub-channel before multiplexing and reduces average transmit pulse energy at filter input in the same way as the above. The normalized peak factor can be reduced by about 6 dB by applying the PPS scheme that does not significantly degrade BER performance in fading condition. The proposed scheme with adaptive transmit power control is effective for economizing transmit power and reducing PMPR. |
