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。

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.

本文证明了对IIR信道输出进行过采样(采样率是输入码率的整数倍)可以转化成单输入多输出的多信道模型，并且不同的信道有相同的AR系数。

In this paper, we prove that oversampling the output of IIR channels can be transformed into a single input multiple output (SIMO) model, and the subchannels have the same AR coefficients.
