Apply the expression to any oversampled situation. We can find that correlation value between sampled points ascends and the influence that the new sampled point acts on PAPR decreases with the increase of the oversampling rate.
理论分析发现,随着过采样率的增加,采样点之间相关性上升,新增加采样点对信号峰值平均功率比的影响下降,系统峰值平均功率比的变化缓慢并趋于稳定。
