In this report, we propose a new PAPR reduction technique by a hybrid algorithm based on a partial transmit sequence (PTS) and adaptive peak power reduction (APPR) method. This technique is used in a system based on Orthogonal Frequency Division Multiplexing (OFDM). OFDM has many orthogonally modulated subcarriers which unexpectedly give a large peak to average power ratio (PAPR) and tends to reduce the power efficiency of a RF amplifier. The input data using the PTS method, a sequence of input data is rearranged for the reduction of PAPR and fed to APPR process. The APPR method controls the peak level of the modulation signal based on an adaptive algorithm which reduces modulation signals over a predefined range. A proposed reduction method consists of these two methods and realizes bolt advantages at the same time. As simulation results, the proposed method shows the improvement on PAPR and also the bit error rate performance of an OFDM system.
