| 摘 要： | 正交频分复用（OFDM）系统的一个主要缺点是信号的峰均功率比（PAPR）很高。提出了一种将随机分割方法与迭代移位搜索加权因子相结合的改进PTS算法。仿真结果表明，改进后的算法在改善PAPR性能和计算的复杂度之间取得了较好的折衷。

| Abstract: | One of major drawbacks of OFDM system is its large peak to average power ratio(PAPR) of transmitted signal.An improved PTS algorithm combining random division and iterative shifting linear searching is proposed.The results of simulation show that the improved PTS method has achieved a good compromise between PAPR performance and computation complexity. |
