Compared with the single carrier systems, orthogonal frequency division multiplexing (OFDM) has many advantages of higher bandwidth efficiency and stronger anti-multi-path ability. However, OFDM technology also has some disadvantages, including the multi-carrier synchronization and higher peak-to-average power ratio. In order to solve the higher peak-to-average power ratio problem, this article combines the double-level optimal search method and Kwon suboptimal method, proposes a threshold-based double-level optimal search algorithm. The method is an improved PTS algorithm and is a linear process. The simulation proves that, with the same optimization grouping parameters and auxiliary information, the new algorithm with a reasonable threshold, which has a smaller loss of reducing PAPR performance, greatly reduces the system complexity.
