摘　　要：部分传输序列(Partial Transmit Sequences,PTS)是一种常用的降低正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)系统峰均功率比(Peak-to-Average Power Ratio,PAPR)的方法,其能确保不给系统带来信号畸变。PTS算法的遍历特点导致计算复杂度大幅提高,文章提出的基于哈达玛矩阵的改进PTS算法将在很大程度上保障信号PAPR的性能,降低计算的复杂度。PTS(Partial Transmission Sequence)is a commonly used method to reduce the PAPR(Peak-to-Average Power Ratio)of OFDM(Orthogonal Frequency Division Multiplexing)system,which ensures not to cause signal distortion for the system.The traversal characteristics of PTS algorithm result in a significant increase in computational complexity.The improved PTS algorithm based Hadamard matrix proposed in this paper greatly ensures the signal PAPR performance while significantly reduces the complexity of the calculation process.
