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
