Simulation of Hybrid DS/FH Spread Spectrum Technique in LEO Satellite Telemetry & Control Link
摘要
Abstract
The city transmission environments of LEO satellite telemetry & control link is described, and the relevant channel models and the typical simulation parameters are introduced. A hybrid direct sequence fre-quency and hopping spread spectrum scheme is proposed. The simulation model is presented firstly, and then anti-jamming performance simulation and analysis axe carried out in the different jamming modes. The simula-tion proves that the proposed scheme can be suited to the LEO satellite link and possesses stronger ant-jam-ming capability under the condition of multi-tone jamming. The research of the thesis has some significance to the anti-jamming performance enhancement of LEO satellite link.关键词
