Partial transmit sequence （PTS） is a promising technique for peak-to-average power ratio （PAPR） reduction in orthogonal frequency division multiplexing （OFDM）. While in optimal PTS, an exhaustive search for all combinations of phase factor sequences is required, this results in huge computation. In this paper, by introducing the orthogonal design, a phase factor sequences algorithm is proposed. The algorithm uses orthogonal table to generate phase factor sequences, and the regular PAPR computation result is then followed by the parameter estimation. The simulation result shows that the proposed algorithm reduces the computation notably and obtains a good PAPR performance approaching the optimal PTS.
