摘要 为了减小SC-FDMA系统中过高的峰值平均功率比(PAPR)造成的非线性失真,同时克服传统PTS方法计算复杂度大的缺点,提出了两种降PAPR的IP-PTS方法:LCC-IP-PTS和迭代LCC-IP-PTS方法.仿真结果表明,LCC-IP-PTS方法在无损系统PAPR性能的情况下大大降低了计算复杂度.迭代LCC-IP-PTS方法在第一种方法的基础上以牺牲仅0.2dB的PAPR性能进一步降低了计算量.这两种方法尤其是第二种实用性强,效率高,适合应用在SC-FDMA系统以及其它OFDM通信系统中. To reduce the nonlinear distortions caused by the high peak-to-average power ration（PAPR）in SC-FDMA systems as well as reduce the computational complexity of conventional PTS methods,two schemes were proposed：LCC-IP-PTS and iterated LCC-IP-PTS.Simulation results show that the LCC-IP-PTS scheme significantly lower the computational complexity at no loss of PAPR performance of the system.While compared to the first method,the second method reduces by more than half of the computational complexity with only 0.2dB loss of PAPR performance.Two schemes especially the second one are practical and efficiency which are perfectly applied into SC-FDMA systems and other OFDM communication systems.
