OFDM峰均功率比降低方法概述
An overview of peak-to-average power ratio reduction techniques for OFDM
【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。
【Abstract】 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.
