### 抜粋

In this paper, we propose a peak-power-reduction (PPR) scheme for a systematic block-coded OFDM signal. In this scheme, peak power of OFDM signal is reduced by adjusting the phase of cluster, which contains only parity-carriers, so as to minimize the peak-to-average power ratio (PAPR) at the transmitter. At the receiver, original signal of parity-carrier is replicated using decided-value of receive data-carriers corresponding to data-bits of code-word. Thus, phase rotation value of the cluster is estimated by comparing the receive signal of parity-carrier and its replica. A reduction of about 2.5dB in peak power and approximately the same BER performance as the case of the ideal decoding are achieved by applying the PPR scheme to an OFDM system with 126 subcarriers in multipath fading condition.
