An PTS optimization algorithm for PAPR reduction of OFDM system

Based on the analysis of PTS (Partial Transmit Sequence) algorithm which is a traditional PAPR (Peak-to-Average Power Ratio)suppression, this paper proposes a new random interleaved segmentation method, which combines random segmentation and interleaved segmentation, that means in the V subsequences, some blocks use random segmentation, while the others use interleaved segmentation. Theoretical analysis and simulation results show that this method can effectively reduce the computational complexity and the amount of calculation, can effectively inhibit the PAPR performance, so as to achieve the purpose of PTS algorithm performance.
