基于OFDM的传输系统的主要限制之一是传输信号的高峰均功率比（PAPR）。本文提出了一种基于剩余数系统（RNS）的降低峰均功率比的OFDM传输方案，该方案利用剩余数系统的特性来控制传输信号的动态范围，避免了降低峰均功率比所带来的非线性失真。实验结果表明，与原始OFDM相比，该方法的峰均比性能至少有5dB的改善。
One of the main limitations for OFDM-based transmission systems is the high Peak-to-Average Power Ratio (PAPR) of the transmitted signals. In this paper, the residue number system (RNS) based OFDM transmission scheme is proposed to reduce the PAPR, which uses the features of RNS to control the dynamic range of the transmitted signals and avoid the nonlinear distortion for the PAPR reduction. Experimental results show that at least 5dB of PAPR performance is improved with the proposed method, compared with the original OFDM.
