For the problem that the peak-to-average-power ratio (PAPR) of the orthogonal freque- ntcy division multiplexing (OFDM) system is high, the dual layered phase sequencing (DLPS) method is made to reduce the PAPR. The method divides the sub-carrier into two layers and each layer uses the suboptimal PTS to reduce the PAPR, so the method reduces the PAPR of the whole OFDM system. The results of the simulation show that the algorithm of dual layered PTS greatly reduced the complexity of the system, while PAPR has been in a situation of better control.
