Abstract

The orthogonal frequency-division multiplexing (OFDM) became the most important technology of the wireless broadband communications system because it achieves high data transmission and is robust to the frequency selective fading channel. However, the major disadvantage of this technology is a high peak-to-average power ratio (PAPR) because it causes signal distortion and high energy consumption. Thus, a new PAPR reduction technique is proposed in this paper. The proposed selective mapping technique (SLM) uses a phase rotation as well as a sliding amplitude weighting factor in frequency domain to generate statistically independent OFDM symbols group. Some subcarrier with high frequency produces many peak points in time domain so that it causes high PAPR. Thus, the basic principle of the proposed scheme is that some subcarrier with low frequency is given to a high amplitude weighting factor and some subcarrier with high frequency is given to a low amplitude weighting factor. In addition, the performance of the proposed SLM is evaluated with computer simulations
