由于数字信号处理(digital signal processing)的领域中,我们处理的信号都是经过采样(sampling)的,而这些信号的采样点数是有限的。因此离散Fourier变换是一个有限维内积空间里的基变换。我们设信号采样的数量为N,则我们的信号向量 x\in\mathbb{C}^N 。在离散场景下我们定义信号(时域下的)自然基: \mathbf{\hat{e}...

Abstract:As one of the key calculation steps of radar signal processing, FFT is essentially a processing process based on data stream. In the past, most of the previous FFT calculations concentrated on the implementation of parallel calculations on a general-purpose computing platform, and the comp...
