正交频分复用（OFDM）系统面临的难题之一是其高峰值平均功率比（PAPR）。本文从计算复杂度、带宽扩展、频谱溢出和性能等方面对不同的OFDM PAPR降低技术进行了综述和分析。讨论了多用户OFDM宽带通信系统中减小PAPR的一些方法。
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.
