摘要
OFDM技术具有抗干扰能力强、频谱效率高、数据传输速率高等优点,但其主要缺点是有很高的峰均功率比(PAPR),影响其的实际应用。现对不同降低OFDM峰均功率比方法分别进行了概述,并给出比较。
Besides a lot of advantages, such as powerful immunity, high spectrum efficiency, higher data transmission speed and so on, major shortage of OFDM is that the multiplex signal, exhibits a very high peak - to - average power ratio（PAPR）. This paper destribes some important PAPR reduction techniques for OFDM systems and shows the differences between them.
