| Abstract(in English) | In this paper, we propose a peak power reduction method based on structure of parity-check matrix for LDPC coded OFDM system, where transmit data sequence is grouped into several clusters on the basis of structure of parity-check matrix. The transmitter structure in the proposed system is similar to the partial transmit sequence and weighting factors (WFs) are estimated with sufficient accuracy by exploiting the decoding property of LDPC code. When LDPC code with code-rate of R=1/2, PAPR of OFDM signal can be reduced by about 2.4dB without significant degradation in BLER performance in attenuated 12-path Rayleigh fading condition. |
