用于降低OFDM系统峰均功率比的 PTS-Clipping 联合算法.基于 IEEE 802.16d 协议的 OFDM 传输系统，研究了峰均功率比（PAPR）较高的原因，在现有 PARR 降低算法的基础上，深入研究了算法之间的最佳联合准则，比较了两种可行的联合算法 PTS-Clipping 和 Clipping-PTS 之间的性能差异，得出了算法联合时的最佳级联顺序-The cause of high PAPR in IEEE 802.16d OFDM system is investigated. Based on the existed algorithms to reduce

the PAPR, the best Combined Rules and Sequence between algorithms are studied. The performances of two possible

combined algorithms (PTS-Clipping and Clipping-PTS) are compared
