论文摘要
在文献中可以很好地理解计算单个通道的FFT。但是，以系统的方式计算多个通道的FFT尚未完全解决。本文提出了一个框架，用于设计一个多通道FFT架构的家族，并使用{\ em折叠}和{\ em Interleaving}设计。本文介绍了三个不同的多渠道FFT体系结构。这些体系结构在输入和输出预处理步骤中有所不同，并且基于不同的折叠集，即执行的不同顺序。
Computing the FFT of a single channel is well understood in the literature. However, computing the FFT of multiple channels in a systematic manner has not been fully addressed. This paper presents a framework to design a family of multi-channel FFT architectures using {\em folding} and {\em interleaving}. Three distinct multi-channel FFT architectures are presented in this paper. These architectures differ in the input and output preprocessing steps and are based on different folding sets, i.e., different orders of execution.
