Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is an efficient scheme for high speed data transmission in communication systems. However, this scheme has inherent problem of a High Peak to Average Power Ratio (PAPR), which causes significant reduction in performance and power efficiency of this scheme. In this paper, we propose a PAPR reduction method based on companding technique for the localized and Distributed Discrete Fourier Transform-Spread OFDM (DFTS-OFDM) systems. The simulation results indicate that the proposed method obtains about 10 dB PAPR reduction compared with simple OFDM systems.
