TLDR
Different OFDM PAPR reduction techniques are reviewed and analysis, based on computational complexity, bandwidth expansion, spectral spillage and performance, for multiuser OFDM broadband communication systems.Abstract:
One of the challenging issues for Orthogonal Frequency Division Multiplexing (OFDM) system is its high Peak-to-Average Power Ratio (PAPR). In this paper, we review and analysis different OFDM PAPR reduction techniques, based on computational complexity, bandwidth expansion, spectral spillage and performance. We also discuss some methods of PAPR reduction for multiuser OFDM broadband communication systems.read more

Peak-To-Average Power Ratio Reduction in OFDM Systems: A Survey And Taxonomy
Yasir Rahmatallah,Seshadri Mohan +1 more
TL;DR: The survey describes the most commonly encountered impediment of OFDM systems, the PAPR problem and consequent impact on power amplifiers leading to nonlinear distortion, and provides insights into the transmitted power constraint by showing the possibility of satisfying the constraint without added complexity by the use of companding transforms with suitably chosen companding parameters.
