Abstract
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.
