其中FFT 的分辨率完全取决于采样时间长度 ,和采样率 ,与零填充无关。 频率分辨率 Δf 并没有变: 依旧是 ,因为“有效采样时长”没变。 只是增加了插值点:频谱曲线变得平滑,看起来像“更细”;实质是对原本 FFT 结果做了sinc 内插**。 方便峰值估计:QIFFT ...
我觉得这是真真正正的读过思考过,也是一个好问题~其实这是在考虑 相干采样时如何避免重复模式 的问题。 目的:避免“相位点重复模式”;如果 和 有公因数,信号的采样点可能在窗口内呈现某种重复格局(比如相位只取有限几个点),会让拟合或谐波 ...
Abstract: Large-scale FFT operations in NR system are highly resource-intensive and computationally complicated, constituting a significant aspect of signal processing. Using high-radix to realize ...
