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...
The Fast Fourier Transform is one of the most important topics in Digital Signal Processing but it is a confusing subject which frequently raises questions. Here, we answer Frequently Asked Questions (FAQs) about the FFT. 1. FFT Basics
A GPS L2C signal acquisition method based on the combination of short time correlation and FFT Zhou Hang,Ba Xiaohui,Chen Jie,Zhang Honglun Abstract: Key words : 0 引言 按照GPS现代化计划,GPS增加了L2C信号作为第二个民用信号。目前,有7颗Block IIR-M卫星和8颗Block IIF卫星发射L2C信号。新增的L2...
用大规模集成电路FPGA(现场可编程门阵列)来实现FFT算法时,需要重点考虑的不再是算法运算量,而是算法的复杂性、规整性和模块化,因为算法的简单性和规整性将更适合大规模集成,更方便于版图设计,而算法的模块化更有利于FFT处理器的灵活扩展。组合数FFT算法和CORDIC(坐标旋转数字计算机)算法结合起来,在计算长点数、可扩展...
