dc.description.abstractIn this paper, we proposed a new PAPR reduction technique using selective mapping (SLM) cascade with adaptive peak power reduction (APPR) methods. This technique is used in a system based on Orthogonal Frequency Division Multiplexing (OFDM). OFDM has many orthogonally modulated subcarriers which unexpectedly produce a peak to average power ratio (PAPR) and tend to reduce the power efficiency of a RF amplifier. A sequence of input data is rearranged by SLM for the reduction of PAPR and then fed into the APPR process in the proposed system. The APPR method controls the peak levels of the modulation signal by an adaptive algorithm. It reduces modulation signals over a predefined range. In simulation results, the proposed method has shown better PAPR reduction compared to the SLM and the APPR. ©2008 IEEE.
