Abstract

Orthogonal frequency division multiplexing (OFDM) has gained popularity as a standard for various high data rate wireless communication systems due to the spectral bandwidth efficiency, robustness to frequency selective fading channels, etc. However, its high peak-to-average power ratio (PAPR) causes significant in-band distortion and high out-of-band radiation when it passes through a nonlinear device such as a high power amplifier (HPA). This paper reviews the main PAPR reduction schemes and introduces their modifications for achieving low-complexity required for practical implementation in wireless communication systems.
