| Abstract(in English) | Orthogonal frequency-division multiplexing (OFDM) has a problem of its high peak-to-average power ratio (PAPR) since the data symbols are multiplexed using a lot of orthogonal subcarrier frequencies. Many works have been done on the PAPR reduction for OFDM signal transmission which are used to re-shape the signal spectrum or waveform such that the different data are not coherently combined at a time. In this paper, we propose a PAPR reduction scheme which exploits the principle of the modulo operation used in Tomlinson-Harashima precoding (THP). A quadrature amplitude modulation (QAM) signal is superimposed on the data symbols to reduce the PAPR. We show by computer simulation that the proposed scheme offers a large PAPR reduction without using any side information. Also we discuss the theoretical bit error rate (BER) performance of the OFDM transmission using the proposed scheme. |
