Orthogonal Frequency Division Multiplexing (OFDM) has recently been focused on in high-data-rate wireless communication research. But the high Peak-to-Average Power Ratio (PAPR) is one of the main obstacles to limit wide applications of OFDM. In this paper, based on the thorough research of selective mapping (SLM) and partial transmit sequences (PTS), the modified SLM schemes with the Riemann matrix...
Orthogonal Frequency Division Multiplexing (OFDM) has recently been focused on in high-data-rate wireless communication research. But the High Peak-to-Average Power Ratio (PAPR) is one of the main obstacles to limit wide application. In this paper, signal scrambling techniques on reducing PAPR are presented, including Selective Mapping (SLM), a modified scheme of SLM by using the standard arrays and...

But the high peak-to-average power ratio (PAPR) is one of the main obstacles to limit wide applications of OFDM. In this paper, these techniques on reducing PAPR are presented, including signal distortion, signal scramming, and block coding. Furthermore, such PAPR solutions...
