Peak-to-Average Power Ratio Reduction of an OFDM Signal Using Signal Scrambling
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 Partial Transmit Sequences (PTS). Furthermore, such PAPR solutions are analyzed theoretically and compared, their performance are obtained by Monte Carlo simulations. Finally， the redundancy of PTS and SLM are analyzed in detail.
