摘要

研究了基于分数阶傅立叶变换(FrFT)的正交频分复用技术(OFDM)，通常称为啁啾OFDM。通过对啁啾OFDM进行相位调制，得到了啁啾OFDM的恒定包络，并对其峰值平均功率比进行了分析。研究表明，恒包络啁啾OFDM (CE-COFDM)比传统OFDM具有更低的PAPR。相位调制器的不同调制指数会产生不同的CE-COFDM的PAPR值。最后，数据速率得到了提高，研究表明它对PAPR产生了轻微的增加。

Peak to average power ratio analysis of a Constant Envelope Chirped OFDM

Orthogonal Frequency Division Multiplexing (OFDM) using Fractional Fourier Transform (FrFT) normally known as Chirped OFDM is studied. The Constant Envelope of the Chirped OFDM is then obtained by phase modulation of the chirped OFDM and then its Peak to Average Power Ratio (PAPR) is analyzed. The study shows the Constant Envelope Chirped OFDM (CE-COFDM) has low PAPR than convectional OFDM. Different modulation Index of the phase modulator produces different PAPR values of CE-COFDM. Finally the data rate was increased and the study shows it produces minor increase in PAPR.
