基于傅立叶变换的电子通信网络信号捕获系统设计

Design of Signal Acquisition System for Electronic Communication Network Based on Fourier Transform

阐述电子通信网络中的弱信号捕获系统,采用稀疏傅立叶变换,引入信号采集器、处理器构成硬件结构,探讨通过窗函数滤波、频域降采样的运行步骤,实现信号捕获过程。。

This paper describes the weak signal acquisition system in the electronic communication network. The hardware structure is composed of sparse Fourier transform, signal collector and processor. The operation steps of window function filtering and frequency domain down sampling are discussed to realize the signal acquisition process.
