摘要

为了分析添加信号的载波频率对正交频分复用(OFDM)信号峰均功率比减小的影响，计算了正交频分复用(OFDM)信号几何降噪方法的峰均功率比(PAPR)分布。假设基带OFDM信号的特征是一个带限的复高斯过程，我们首先回顾了减小PAPR的几何方法的原理，并进一步给出了PAPR减小方法的渐近分布。

Frequency based asymptotic distribution of the PAPR for geometric adding signal approach in OFDM signals context

The distribution of the peak-to-average power ratio (PAPR) for geometric method of PAPR reduction in orthogonal frequency-division multiplexing (OFDM) signals is evaluated in order to analyse the influence of the carrier frequency of adding signal on the PAPR reduction. Assuming that the baseband OFDM signal is characterized as a band-limited complex Gaussian process, we first recall the principle of the geometric approach for PAPR reduction, and we further develop an asymptotic distribution of the PAPR for the method of PAPR reduction.
