| 释义 |
- 过采样率：在数字信号处理中，过采样率是指采样频率与信号的奈奎斯特频率之比。过采样可以提高信号的分辨率，降低噪声，提高信号质量。

电子、通信与自动控制技术 过采样 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。
