跳频卫星信号传输波形设计研究
Research on Waveform Design for Transmission of Frequency Hopping Satellite Signal
摘要
Abstract
Frequency hopping communication is a basic means to fight against all kinds of malicious interferences,and has been widely used in satellite communication system.Aiming at the transmission requirement of broadband high-speed frequency hopping satellite communication,a kind of anti-jamming strategy is proposed for frequency hopping satellite communication system,which further improves the performance of the system based on the frequency hopping communication.Through the establishment of a complete broadband high-speed frequency hopping satellite communication system simulation model,combined with efficient LDPC code,π/4-DQPSK modulation,interleaving and other techniques,the optimization of transmission waveform simulation is designed.Theoretical analysis and simulation results show that with the designed waveform and Eb/N0 of not less than 6.2 dB,the system anti-barrage jamming performance is not lower than 22 dB.关键词
