摘要 利用预留载波法峰值抑制原理,提出了一种采用峰值抵消策略的PTS方法.该方法把一些部分传输序列看作PAPR抑制载波所对应的时域序列,通过选择部分传输序列和相位旋转因子进行逐步叠加将潜在的峰值消除,最后构成待发送的OFDM符号.由于总的迭代次数有所减少,并且每次迭代过程中只需要处理少数波峰点的样值,因此复杂度较低.仿真结果显示,新的PTS方法具有良好的PAPR抑制性能. Based on the basic idea of Reserved Tone PAPR reduction algorithm,this paper presents a novel PTS which uses the scheme of peaks counteraction. The method regards some partial transmit sequences as the time-domain signals corresponding to certain PAPR reduction tones. By selecting proper partial transmit sequence and phase factor,the partial transmit sequences are accumulated one by one to counteract the potential peaks till one whole OFDM sequence is formed. Since the total iteration times decrease to some extent and only a few samples with high peaks need to be processed in each time iteration,this method has low complexity. Simulation results show that the proposed method has good PAPR reduction performance.
