摘要：

讨论了通过FFT融合实现频域抗干扰和载波多普勒频偏快速捕获的高效数字化方案,分析了融合设计需要解决的采样率、FFT点数、分时复用等关键技术问题,给出了一种可应用于低轨扩频通信系统的高效实现频域抗干扰和PMF-FFT并行捕获的接收机结构,节省了星上接收机等处理资源。

关键词: 频域抗干扰, 并行捕获, 直接序列扩频, 低轨卫星

Abstract:

This paper introduces a high-efficiency co-design method for frequency-domain anti-jamming and parallel acquisition with FFT,analyzes such key problems as sample frequency,FFT calculation points,time-division reuse,etc.,and proposes a baseband processing structure for implementing frequency-domain anti-jamming and parallel acquisition high-efficiently in the DSSS LEO satellite communication system.

Key words: anti-jamming;parallel acquisition;DSSS;LEO satellite
