基于DFT的DS/FH混合扩频通信系统研究

本文分析了DS/FH混合扩频通信系统干扰抑制需求,并以此为基础设计了一种在中频段进行的重叠加窗调制离散傅里叶变换窄带干扰抑制方法,给出了基于重叠加窗调制DFT的抑制干扰系统结构,并进行了性能仿真。

This paper based on the analysis in DS/FH spread spectrum communication system interference suppression requirements on the design of overlapping windowed discrete modulation in the band performed a Fourier transform(DFT) for narrowband interference suppression method is given based on overlapping windowed DFT modulated interference suppression system architecture and performance simulation.
